Given: A corporation has a market capitalization of $24,000,000,000 with 250M outstanding shares.

To calculate the price per share. We will have to divide the market capitalization with outstanding shares.

We have the market capitalization as $24,000,000,000

The number of outstanding shares is 250,000,000

Price per share= Market capitalization/ Number of outstanding shares

​=$24,000,000,000/250,000,000

=96

​The price per share is obtained to be $96.

Given: Qual Comm, Inc. instituted a4−for−1 split in November.  After the split, Elena owned 12,800 shares.

To find the number of shares owned before the split.

We will use the fact that 4−for−1split means the number of share after the split gets four times.

There is 4−for−1 split.

Hence the  number of share after the split gets four times.

Therefore the number of shares before the split will be:

Number of shares after the split /4

=12800/4

=3200​

We have the statement: Perception is strong and sight is weak.

In strategy, it is important to see distant things as if they were close and to take a distanced view of close things.

The given statement implies that the perception of the value per stock is strong and might strongly influence any decision-making of an investor, while the investors don’t tend to notice the true reason of a stock split .

This is way it is important to see distant things as if they are close, such that an investor can see the true reason by stock splits and can take them into account for any decision-making.

A split does not have any meaningful benefit to the investor as the main reason of the split is the perception.

The perception of the value per stock is strong and might strongly influence any decision making of an investor.

Given: Jon noticed that most traditional splits are in the form of x−for−1

He says that in those cases, all you need do is multiply the number of shares held by x

and divide the price per share by x to get the post-split numbers.

To verify Jon’s method works to determine the post-split price and shares outstanding for Hansen Natural Corporation which executed a 4−for−1 split on July 10 with 22,676,800 outstanding shares and a market price of $203.80 per share before the split.

We will have to find the number of shares after the split.

Now we have four for one split.

This implies that the number of shares will become four times.

Now before the split there were 22,676,800 shares.

Hence after the split there will be: 22,676,800×4=90,707,200 shares Now the price will get one fourth of the before the split.

Hence the price per share after the split will be:

1/4×203.80=$50.95

Hence the number of shares were multiplied by x=4

whereas the price was divided by it after the split.

We have verified that Jon’s method works to determine the post-split price and shares outstanding for Hansen Natural Corporation which executed a 4−for−1 split on July 10 with 22,676,800 outstanding shares and a market price of $203.80 per share before the split.

 Page 50 Exercise 8 Answer

Given: Monarch Financial Holdings, Inc. executed a 6−for−5 traditional split on October 5.

Before the split there were approximately 4,800,000 shares outstanding, each at a share price of $18.00.

To determine the post-split share price and the number of shares.We will use the worth of each share.

Now we know that there is6−for−5 share split.

Before the split the number of shares were 4,800,000 shares Hence after the split it will be multiplies by 6/5 Hence we get: 6/5×4800000=5,760,000

There is a6−for−5  split share.Hence the price will get 5/6  the price before the split.

Now each share was originally$18.00

Hence after the split it will be : 5/6×18=$15.00

The post-split share price is $15.00 The number of shares outstanding is 5,760,000.

Given: Monarch Financial Holdings, Inc. executed a 6−for−5 traditional split on October 5.

Before the split there were approximately 4,800,000 shares outstanding, each at a share price of $18.00.To compare the results from part a. with that obtained by using Jon’s method.

Jon’s method says that 6−for−5 is the same as 1.2−for−1. We will find the answer using 1.2-for-1 and then compare.

Now we know that there is1.2−for−1 split Before the split the number of shares were 4,800,000 shares

Hence after the split it will be multiplies by1.2

Hence we get:

1.2×4800000=5,760,000

There is a 1.2−for−1 split. Hence the price will get divided by 1.2

Now  each share was originally$18.00

Hence after the split it will be: 18/1.2=15.00

Hence we get the same answers.

We obtain the same answers by using both the methods of that in part a and by John’s method.

At that time Krista owned 205 shares of that stock. The price per share was $33.99.

After the split, Krista received a check for a fractional part of a share.To find the amount of the check.We will use the fact that 3−for−2

split means we will have to multiply two third for the original price.

Now we know that there is3−for−2 share split.

Before the split the number of shares were205 Hence after the split it will be multiplies by 3/2

Hence we get 3/2×205=307shares. there is 3 -for-2-share split

Hence the price will get two third of the original price Hence after the split it will be:2/3×33.99=22.66

Now the fractional part .5 is exchanged for the monetary.

Hence the amount of the check was $11.33.

Krista received a check of $11.33.

Cengage Financial Algebra 1st Edition Chapter 4 Exercise 4.1  Page 178 Exercise 2 Answer

We are given : Purchase price=m dollars

Down payment rate​=20%

=20/100

=0.20.

Monthly payment=x dollars Number of months =24.

We have to express the finance charge algebraically.

In the question, first we will find the down payment .

Then, find the total amount of monthly payments .

Calculate the total cost and then, find the finance charge.

Firstly, we will find the down payment.

As, down payment is the product of the down payment rate and the purchase price.

Therefore,Down payment=Down payment rate×purchase price

Down payment=0.20×m

Down payment=0.20m .

​Now, we will find the total amount of monthly payments .

As, the total amount of monthly payments is the product of the number of months and the monthly payment.

Therefore,Total amount of monthly payments=Number of months×Monthly payment

Total amount of monthly payments=24×x

Total amount of monthly payments=24x.​

We will find the total cost .

As, the total cost is the sum of the down payment and the total amount of monthly payments .

Therefore,Total cost=Down payment+Total amount of monthly payments

Total cost=0.20m+24x.

Now, we will find the finance charge .

As, the finance charge is the difference between the total cost and the purchase price .

Therefore,Finance charge=Total cost−Purchase price

Finance charge=0.20m+24x−(m)

Finance charge=24x+0.20−1

Finance charge=24x+(0.20−1)m

Finance charge=24x−0.8 .

The finance charge is 24x-0.80.

Q 3) what type of accounts are eligible for FDIC insurance?

Trust accounts report Trust account is a savings account deposited in the name of a trustee who controls it during his lifetime, after which the balance is payable to a pre-nominated beneficiary There are two types of Trust Accounts revocable and irrevocable, the extent of FDIC insurance depends on which out of these 2, our account is.

A revocable trust is that, which assigns beneficiaries, receiving the funds of trust after the death of the owner.

But the trust can also be terminated or there can be a change of terms by the owner.

A revocable trust may become an irrevocable trust once the owner dies because effectively there is no longer an option to cancel or change the trust. In a revocable trust, the owner is considered the depositor and the account are only eligible for 250,000 of FDIC insurance coverage.

However, if a bank fails after a trust owner has died but before the trust has been paid out, the beneficiaries are considered the depositors and each is entitled to 250,000 in coverage.

To find: Some employers allow employees to have money deducted from their accounts and automatically placed into a savings account.

Interview three adults working in different professions.

Ask them about employer-sponsored savings plans. Prepare a report on the findings.

A employer-sponsored savings plan is used by employees who elect to save a portion of their paycheck in an investment account.

This type of plan is set up by the employers, who often sponsor the plan as well and these plans are often based around retirement.

There are annual contribution limits, but also tax benefits accompanying this type of plan.

It could be possible to withdraw funds early (with some additional fees) or to bottom against your account balance.

The employees are fully responsible in what their money is invested in and the employees can take their employer-sponsored savings plan with them when they change work (change their employer).

To find:  Visit a local bank. Get brochures they offer about their services. If the brochures are two-sided, take two of each so you can cut them out and paste them onto a poster board.

Pick several services to highlight. Cut out the portions of the brochures that explain each service.

Give each service an original, short title, and print out your title.

Organize the titles and descriptions of the banking services onto a poster board.

The answers to this questions will vary very strongly.

You will need to pick up brochures at your local bank about their services.

Per service, you will need to pick a title. However, this could be very easy as the brochures tend to use titles to separate the different (most important) services.

If a title has not been specified, then either use the name of the service as title or use a (very) short description of the service.

Organize the titles in some manner. For example, organize the titles from cheapest to most-expensive service.

To find: The Rule of 72 is a method for quickly estimating how many years it will take principal to double, assuming the interest was compounded.

Go to the library and/or use the Internet to research the Rule of 72 beyond what was presented in Lesson 3-7.

Prepare some examples to illustrate the rule. Discuss the history and the use of the rule. Display your research on a poster board.

The Rule of 72 is used to determine the time it takes for an investment to double.

To use the rule of 72 , you require the knowledge of the annual rate of return (or annual interest rate).

The rule of 72 states that the product of the rate of return and the number of years (time) should be roughly equal to 72 .

On equivalently, the time it takes to double your investment is 72 divided by the annual interest rate

Although, most people attribute the rule of 72 to Albert Einstein.

The Rule of 72 is used to determine the time it takes for an investment to double.

Page 168 Problem 11 Answer

Given: The graph showing the catching of counterfeit bills in the U.S. is as follows:

To find: If the pattern of catching counterfeit bills before and after circulation follows the same pattern of increases and decreases.

Solution: In the year2000 and2005, the dollars found before and after circulation both increased from the year before but at a different rate.

In the year2001 and 2004, compared to their respective previous years the dollars found after circulation increased but dollars found before circulation decreased the year 2002, both the dollars found before and after circulation decreased but at a different rate.

Similarly, in the year2003, dollars found after circulation decreased whereas dollars found before circulation increased.

Hence we can see that the pattern of catching counterfeit bills before and after circulation do not follow the same pattern of increases and decreases

On examining the graph drawn in the previous part of the question we can observe that the graph showing the catching of counterfeit bills before and after they enter circulation are not similar nor are they completely opposite.

It is a mixture of increases and decreases and both the graph does not show any relation between them.

Thus, the pattern of catching counterfeit bills before and after circulation does not follow the same pattern of increases and decreases.

To find: Write the formula to find the present value of an x-dollar balance that is reached by periodic investments made semiannually for y years at an interest rate of r.

PV=X×(1−1

(1+(r/2))^yx2)/(r/2)

Periodic payment (PMT) = X

Time (n) =yx²

Interest rate (r) =r/2

PV=PMT×(1−1/(1+r)/n)/r

=X×(1−1(1+(r/2))^yx2)/(r/2) on simplifying

=X⋅(1−1(1+(r/2))^2y)/r/2

Hence the present value is X⋅(1−1(1+(r/2))/2y)/r/2

To find: How might those words apply to what has been outlined in this lesson?

In order to start setting financial goals, you need to take into account what you can currently afford to save (thus determine how much money you have left over after you have paid all bills and bought all necessary items such as food and clothes).

This is necessary, because else you will start making debts to pay for your food or bills, which will not aid your overall financial situation.

Moreover, it is also useful to look ahead at the future value savings, such that you know what you will earn from these future value savings in the future and also such that you can determine what you will do with this money in the future.

Hence the answer is In order to start setting financial goals, you need to take into account what you can currently afford to save.

Given: Periodic deposit amount(P)=$5000

Annual interest rate expressed as a decimal(r)=0.045

Number of times interest is compounded annually(n)=1

To find: The account balance(B) if the length of investment in years(t) is 21 years

Solution: We will find the account balance using the formula for future value:

B=P((1+r/n)^nt−1)/r/n

We will substitute the values in the formula to find the account balance

B=P((1+r/n)^nt−1)/r/n

=5000((1+0.045/1)^(1)(21)−1)/0.045/1

=5000((1.045)21−1)/0.045

≈168915.68

Read and Learn  More Cengage Financial Algebra 1st Edition Answers

years=5000×21=$105,000

Balance in the account after 21 years=$168,915.68

Interest they will earn after 20 years=$56,857.11

To find: How much more interest would Rich and Laura earn by retiring after 21 years?

Solution: We will first find the interest earned if they retire after 21 Years Then we will compare it with the interest earned if they retire after 20 years.

We will first find the interest Rich and Laura will earn if they retire after 21 year.

Interest= Account balance− amount deposited

=168,915.68−105,000

=$63,915.68

The interest they will earn if they retire after 20 years is $56,857.11. So they will earn $7058.57 more in interest.

Rich and Laura would earn$7058.57 interest more by retiring after 21 years.

Given: Linda and Rob open an online savings account that has a 3.6% annual interest rate compounded monthly.

If they deposit $1,200 every month, $173,022.87  will be in the account after 10 years

To find: If opening an account at a higher interest rate for fewer years would have assured Linda and Rob at least the same final balance

Solution: We will calculate the future value using the formula:

B=P((1+r/n)^nt−1)/r/n

We can see from the formula that the value of the deposit will increase if the rate of interest is higher.

So, if the rate of interest is higher we will achieve the amount they will receive at the current interest rate in fewer years.

Thus, opening an account at a higher interest rate for fewer years would give Linda and Rob at least the same final balance.

Yes, opening an account at a higher interest rate for fewer years would have assured Linda and Rob at least the same final balance.

Page 158 Problem 4 Answer

Given Example 1

To do: During the computation of the numerator, is the 1 being subtracted from the 20. Explain your reasoning

Firstly we have the solution as

B=5,000((1+0.045/1)¹(20)−1)/0.045/1

where 1 is subtracted from the before computation but not the exponent means that (1+0.045/1)1(20) is computed first and then one is subtracted from the value not from 20

Therefore, No, using the order of operations (1+0.045/1)1(20) is computed first and then 1 is subtracted from the value not from 20

To find: Suppose that you invest $2,000 at a 1% annual interest rate.

Use your calculator to input different values for t in the compound interest formula.

What whole number value of t will yield an amount closest to twice the initial deposit?

B=P(1+r/n)^n×t

40000=20000(1+0.06/1)^1×t

40000=20000(1.06)^t

2=(1.06)^t

ln2=ln(1.06)^t

ln2=tln(1.06)

ln2/ln1.06=t

​Evaluate: t=ln2/ln1.01≈70

To find: Albert Einstein noticed a very interesting pattern when an initial deposit doubled.

In each of the three examples above, multiply the value of t that you determined times the percentage amount.

For example, in a. multiply t by 1. What do you notice?

First example of part (a)

Result part (a):

t=70

r=1%

​We need to multiply the value of t by the percentage amount of r.

t×r=70×1=70

Second example of part (b)

Result part (b):

t=35

r=2%

We need to multiply the value of t by the percentage amount of r.

t×r=35×2=70

Third example of part (c)

Result part (c):

t=12

r=6%

​We need to multiply the value of t by the percentage amount of r.

t×r=12×6=72

We notice that the product in all three examples is equal to 70 or 72 , thus the product is always close to 72 .

Hence We notice that the product in all three examples is equal to 70 or 72 , thus the product is always close to 72 .

How To Solve Cengage Financial Algebra Chapter 3.7 Banking Services

Page 160 Exercise 9 Answer

To find: Einstein called this the Rule of 72 because for any initial deposit and for any interest percentage, 72 (percentage) will give you the approximate number of years it will take for the initial deposit to double in value.

Einstein also said that “If people really understood the Rule of 72 they would never put their money in banks.”

Suppose that a 10-year-old has $500 to invest.

She puts it in her savings account that has a 1.75% annual interest rate.

How old will she be when the money doubles?

Given:r= Interest rate =1.75%

By Einstein’s rule of 72 , we know that the product of the time $t$ and the interest rate percentage $r$ needs to be equal to 72 when we double the money.

t×r=72

In this case: r=1.75

t×1.75=72

Divide each side by 1.75:

t=72

1.75

≈41

This then means that the money doubles in roughly 41 years.

Since she is currently 10 years old, the money will double when she is roughly 10+41=51 years.

Hence the answer is 51 years old

Given; Barbara deposits 3,000 in a one-year CD at 4.1 % interest, compounded daily.

To find: What is the APY to the nearest hundredth of a percent?

The APY using the compound interest formula and the simple interest formula.

​B=p(1+r/n)^nt

B=3,000(1+0.041/365)^365×1

B=3125

I=3125−2,000

=125

I=prt

=I/pt

=125/3,000×1

=0.041%

​r= 4.1 %

The annual percentage yield is 4.10 %

APY can also be found by using the formula APY (1+r/n)ⁿ⁻¹

APY=(1+r/n)ⁿ⁻¹

APY=(1+0.041/365)³⁶⁵⁻¹

APY≈0.041=4.1%

​The annual percentage yield is 4.1 %, which is the same as the previous answer

Hence The APY to the nearest hundredth of a percent is found to be 4.10 %

Page 145 Problem 4 Answer

Given; One is an account that pays 2.78 % compounded daily. The other account pays 3.25 % compounded quarterly.

To find: Would either of these accounts provide Nancy with a better return than her current account? If so, which account?

To find which account earns the most money compute the ratio of A/P for each account then compare them.

For the second account: r=2.78% and the compound rate is continuous, therefore:

A/P=e^2.78%≈1.028

For the Second account:r=3.25% and n=4  therefore:A/P

=(1+3.25%/4)⁴ ≈1.032

1.032>1.028

The second account earns more money because its ratio of Future Value to Initial Value higher than the other account.

Hence we conclude that The second account earns more money because its ratio of Future Value to Initial Value higher than the other account.

Given ; Consider an amount x deposited into a CD at 2.4 %  interest compounded daily, and the same amount deposited into a CD at the same rate that compounds monthly.

To find : Explain why, after 1 year, the balance on a CD that compounds daily is greater than the CD that compounded monthly.

Find the APY using the compound interest formula and the simple interest formula.

​B=p(1+r/n)^nt

B=x(1+0.024/365)^365×1

Subtract the principal from the new balance.

I = x(1+0.024/365)^365×1

=x(1+0.024/365)^365×1

−x/x×1

APY can also be found by using the formula APY=(1+r/n)ⁿ⁻¹  is the interest rate and n is the number of times interest is compounded per year.

1-Year CD with both of them at the same 2.4 % APR interest rate, and compare how much interest you have at the end of the year. Both credit interest monthly.

Since MoBank compounds monthly, you are getting 2.4 5/12 =0.002 every month.

so it much less that the daily compounded interest Since MoBank compounds monthly, we are getting 2.4 % /12= 0.002 every month.

so it much less that the daily compounded interest

Page 148 Problem 7 Answer

According to question,

The words imply that if you want to earn a lot of money through interest, then you need to start with a lot of money.

Given: An elite private college receives large donations from successful alumni.

The account that holds these donations has $955,000,000 currently.

Find: How much would the account earn in one year at 5.33% if the interest was compounded daily.

According to question,

B=p(1+r/n)^nt

=955,000,000(1+0.0533/365)^365×1

≈1,007,278,530.91

​Then,The interest is the difference between the balance and the principle:

I=B−p

=1,007,278,530.91−955,000,000

=52,278,530.91

​Hence, The required answer is: $52,278,530.91

Given: An elite private college receives large donations from successful alumni.

The account that holds these donations has $955,000,000 currently.

Find: If the money is used to pay full scholarships, and the price of tuition is $61,000 per year to attend, how many more students can receive full four-year scholarships if the interest was compounded daily rather than using simple interest.

According to question,Result of first part is:$50,901,500 (simple interest)

Result of second part is:$52,278,530.91 (compounded daily)

The differences of the interests:

$52,278,530.91−$50,901,500=$1,377,030.91

Hence, As we have $1,377,030.91 more when using daily compounding.

Then according to question,Every student receives a tuition of $61,000per year, which is thus$61,000×4=$244,000 per full four-year scholarship.

Then, The number of additional students that can then receive a full four-year scholarship are then the additional interest divided by$244,000.

$1,377,030.91

$244,000≈5.6436≈5

Therefore, 5 more students can receive a full four-year scholarship.

Hence,5 more students can receive a full four-year scholarship.

Cengage Financial Algebra 1st Edition Chapter 1 Exercise 1.9 The Stock Market Page 55 Problem 5 Answer

It is given: I believe non-dividend stocks aren’t much more than baseball cards.

They are worth what you can convince someone to pay for them.

The analogy of non-dividend stocks and baseball cards represents the similarity of two things in which value is determined by the demand, so they can be worthless in one moment and in another very expensive.

If we talk in terms of baseball cards, their value might vary a lot.

The card of some barely known baseball player is worth very little. It has only its intrinsic value.

However, if he becomes very famous, the value of the card increases drastically.

Some card-lovers are ready to pay huge amounts just to get that particular card.

And if people buy cards for their pleasure, that is completely fine.

But, if some person buys the card, or the stock share, with the hope to sell later for a higher price, we can notice the similarity.

Gaining profit from both the investments is dependent on the random value that the buyers will decide to give.

Cengage Financial Algebra 1st Edition Chapter 1 Exercise 1.9 The Stock Market Page 56 Exercise 7 Answer

We are given : Annual dividend per share=$1.60

Friday closing=$44

Friday’s net change=$0.35.

By looking at the yields for Wednesday, Thursday, and Friday, we get that they are decreasing .

We have to explain why this decrease is not “bad news” to the investor who owns stock in Revreg.

The yield falls because of rising share prices, not because of falling dividends per share. Since

the dividend level has not changed, this is not “bad news” for the investor who owns shares in Revreg.

You will receive the same dividend amount regardless of the drop in performance.

And, another reason could be that the stock is a growth stock as its prices rise sharply every day.

Remember, growth stocks are bought for capital gains rather than dividends- buy low and sell high.

The decrease is not “bad news” to the investor who owns stock in Revreg because the amount of dividends did not actually decrease and there is possibly a growth stock .

Wednesday closing=$61

Net change on Wednesday=−0.85 .

By looking at the yields for Monday, Tuesday, and Wednesday we get that they are increasing.

We have explain this increase is not “good news” to the investor who owns stock in

The yield is increasing and the reason is the price decrease of the stock, not because the dividends are increasing.

As the dividends are not increasing, the yield increase is not necessarily ‘good news’ to the investor who owns Zeescore stock because he or she will still receive the same amount of dividends despite the increase in yield.

The increase is not “good news” to the investor who owns stock in Zeescore because there is no increase in the amount of dividends.

=0.0634

Price of stock=$46

Annual dividend=$2

Time( in years)=14 years.

We have to determine which is higher, the yield on the stock or the interest rate on the bond.

Firstly, we will find the yield and then the interest.

We will find the yield.

yield =dividend price of stock

yield=2/46

yield=0.04347

yield=4.347% .

By rounding off ,we get :yield=4.4%.

We will find the interest after 14 years.

Interest after 14 years=14× interest after 1 year

Interest : =14×63.4

=88.76%.​

The interest rate on the bond is higher than the yield on the stock as the interest rate is 88.76%.

Page 56 Exercise 18 Answer

We are given: Cost of shares=$1000

Annual interest=6.34% or 6.34/100

=0.0634

Time(in years)=1,14 years.

Bond matures after one year when :

Amount received=initial amount+ interest of 1year

Amount received=1000+0.0634×1000×1

Amount received=1000+63.4

Amount received=$1063.4.

Bond matures after 14 years when :

Amount received=1000+14(0.0634)(1000)

Amount received=1000+14(0.0634)

Amount received=1000+887.6

Amount received=$1887.6.

We are given: Annual dividend per share=$2.46

Selling price per share=$54.24.

Selling price per share underwent a 3-for-1 split.

We have to find the new price of one share after the split.

As, we are given3−for−1split, therefore, the selling price before split will be divided by 3.

Therefore,Selling price after split = Selling price before split ÷3 Selling price after split =$54.24÷3 Selling price after split =$18.08.​

The new price of one share after the split is$18.08.

Page 56 Exercise 20 Answer

We are given: Annual dividend per share=$2.46

Selling price per share=$54.24

Number of shares=100.

The number of shares underwent a 3-for-1 split.

We have to find the number of shares you own after the split.

As we are given3−for−1split, therefore, the number of shares is multiplied by 3.

Number of shares after split = Number of shares before split ×3

Number of shares after split=200×3

Number of shares after split =600.

​The number of shares you own after the split is600.

Given;  x dollars earn in one day at an interest rate of 5 % compounded daily

To find; Express the answer algebraically.

Accounts that pay interest daily earn interest every day.There are 365 days in a year.

r=5

r=0.05

​t=1 day

t=1 day =1/365 years

simple interest I=prt

I=1,000×0.05×1/365

≈0.13 interest to the principal. 1,000+0.13=1,000.13

The first day’s interest is approximately 13 cents, so the new balance is 1,000.13.

This larger principal is used to compute the next day’s interest

Hence we conclude that The first day’s interest is approximately 13 cents, so the new balance is 1,000.13.

This larger principal is used to compute the next day’s interest

We have to find that how might those words apply to what you learned in this lesson

In the old days, a man who would save money was called a miser, because they just saved their money and didn’t earn anything with this money.

Thus the man wouldn’t profit from saving that money and also wouldn’t use this money for some other purpose.

However, nowadays, it is very unique and a kind of miracle to find someone who saves money, because it is not profitable to start saving money at an older age (as time is crucial in making savings grow) and thus you won’t gain much on your money (we do earn some due to compound interest).

Thus if you want to profit the most of your savings, then we need to start saving at a young age, but most people don’t tend to start saving at a young age and thus it is a kind of miracle to find someone who do as such.

A miser just saved their money and didn’t earn anything with this money.

However, nowadays someone who saved money is a wonder, because they would have to start at a young age if they want to profit from their savings.

We have given a table,

We have to find the missing amounts in the table.

We will find by using above information.

No principle amount initially thus

(1) Opening balance = 0

(1) Deposit on 10 August = $4,550

(3) The principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle = Opening balance + Deposit − Withdrawal

=0+4550−0

=4550

(4) The interest is the product of the principle, interest rate and time in years:

I=prt

=4550×0.04×1/365

≈0.50​

Thus interest rate is $0.5

(5)  Ending Balance = principal+interest

Ending Balance =4550+0.5=4550.50

ending balance is $4,550.50

(6)  Next day opening = previous day ending balance

Opening bal aug 11=4550.50

(7)  Deposit on August 11=300

(8)  principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle = Opening balance + Deposit − Withdrawal

=4550.50+300−0

=4850.50

​(9) The interest is the product of the principle, interest rate and time in years:

I=prt

=4850.50×0.04×1/365

≈0.53interest rate is $0.53

(10)  Ending Balance = principal+interest

Ending balance =4850.5+0.53=4851.03

(11)  Next day opening = previous day ending balance

Opening bal aug 12=4851.03

(12)  withdrawal=900

(13)  The principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle= Opening balance + Deposit − Withdrawal

=4851.03+0−900

=3951.03

(14)  The interest is the product of the principle, interest rate and time in years:

I=prt

The account pays 3.45% interest, compounded daily.

On December 19 she deposited $500, and on December 20 she withdrew $2,500.

By using this data we will fill all the blanks in the table.

(1)  no principal amount initially

Thus opening balance is = 0

(2) Deposit = $6000

(3)  Withdrawal =0

(4) The principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle = Opening balance + Deposit − Withdrawal

​(6)  Ending Balance = principal+interest

Ending Balance =6000+0.57=6000.57

(7)  Next day opening = previous day ending balance

Opening bal =6000.57

(8)  Deposit =500

(9)  Withdraw =0

(10)  The principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle = Opening balance + Deposit − Withdrawal

=6,000.57+500−0

=6,500.57

Page 142 Exercise 13 Answer

Given : On May 29, Rocky had an opening balance of x dollars in an account that pays 3% interest, compounded daily. He deposits y dollars.

We have to express his ending balance on May30 algebraically.

We will use above formula .

Here, Consider that the deposit occurs on May 23

So, p=Principle

=Opening balance+Deposit

=$(x+y)

r=Interest rate

=3%

=0.03

t=Time in years

=1day

=1/365years (as there are 365 days in a year)

The interest is the product of the principle, interest rate and time in years:I=prt

=(x+y)×0.03×1/365

=x×3/100×1/365

=3(x+y)/36,500

The ending balance is then the principle increased by the interest: Ending balance

=p+I

=x+3(x+y)/36,500

=36,500x+3x+3y/36,500

=36,503x+3y/36,500

Now, p=Principle=ClosingbalanceMay29

t=$(36,503x+3y/36,500)

r=Interest rate

=3%

=0.03

The interest is the product of the principle, interest rate and time in years:I=prt

=(36,503x+3y/36,500)×0.03×1/365

=(36,503x+3y/36,500)×3/100×1/365

=(36,503x+3y/36,500)×3/36,500

=3(36,503x)+3(3y)/36,5002

=109,509x+9y/1,332,250,000​

The ending balance is then the principle increased by the interest:Ending balance =p+I

=36,503x+3y/36,500+109,509x+9y/1,332,250,000

=36,500(36,503x)+36,500(3y)/1,332,250,000+109,509x+9y/1,332,250,000

=1,332,359,500x+109,500y/1,332,250,000+109,509x+9y/1,332,250,000

=1,332,359,500x+109,500y+109,509x+9y/1,332,250,000

=1,332,469,009x+109,509y/1,332,250,000

Hence, The ending balance on May 30 is 1,332,469,009x+109,509y/1,332,250,000.

Therefore, The ending balance on May 30 is 1,332,469,009x+109,509y/1,332,250,000.

Ending balance =p+I

=(P+D)+(P+D)/18,250

=(P+D)(1+1/18,250)

=(P+D)(18,250/18,250+1/18,250)

=(P+D)(18,251/18,250)

=18,251(P+D)/18,250

(4)  The opening balance on February 3 is the ending balance on the previous day and thus is the ending balance on February 2.

Opening balance on February 3= Opening balance on February 2

=18,251(P+D)/18,250

(5)  The principle used to compute interest is the new balance, which is the opening balance increased by the deposit and decreased by the withdrawal.

Principle = Opening balance + Deposit − Withdrawal

=18,251(P+D)/18,250+0−W

=18,251(P+D)/18,250−W

(6)  The interest is the product of the principle, interest rate and time in years:

I=prt

=(18,251(P+D)/18,250−W)×0.02×1/365

=18,251(P+D)−18,250W/18,250×2/100×1/365

=18,251(P+D)−18,250W/18,250×1/18,250

=18,251(P+D)−18,250W/18,2502

=18,251(P+D)−18,250W/333,062,500​

(7)  The ending balance is then the principle increased by the interest:

Ending balance =p+I

=18,251(P+D)/18,250−W+18,251(P+D)−18,250W/333,062,500

=18,251(P+D)−18,250W/18,250+18,251(P+D)−18,250W/333,062,500

=18,250(18,251)(P+D)−333,062,500W/333,062,500+18,251(P+D)−18,250W/333,062,500

=333,080,750(P+D)−333,062,500W/333,062,500/+18,251(P+D)−18,250W/333,062,500

=333,080,750(P+D)−333,062,500W+18,251(P+D)−18,250W/333,062,500

=333,099,001(P+D)−333,080,750W/333,062,500

Therefore,

1)The principle used to compute interest is the new balance is P+D

2)Interest = =P+D/18,250

3) Ending Balance =18,251(P+D)/18,250

4)Opening Balance =18,251(P+D)/18,250

5)The principle used to compute interest =18,251(P+D)/18,250−W

6)The interest is the product of the principle, interest rate and time in years:  =18,251(P+D)−18,250W/333,062,500

7)Ending Balance:- 333,099,001(P+D)−333,080,750W/333,062,500

How To Solve Cengage Financial Algebra Chapter 3.4 Banking Services

Cengage Financial Algebra 1st Edition Chapter 3 Exercise 3.4 Banking Services Page 142 Exercise 16 Answer

Given: George had an opening balance of m dollars in an account that pays 2.25% interest compounded monthly.

On the last day of the month, he made a deposit equal to twice his opening balance.

We have tp express his ending balance on the last day of the month algebraically.

We will use above formula .

Here, Opening balance =m

Deposit =2m (twice the opening balance)

p  =Principle

= Opening balance + Deposit

=m+2m

=3m

​r= Interest rate

=2.25%

=0.0225

​t=Time in years

=1month

=1/12 years  (as there are 12 months in a year)

Now,The interest is the product of the principle, interest rate and time in years: ​I

=prt

=3m×0.0225×1/12

=3m×225/10000×1/12

=3m×9/400×1/12

=(3m)(9)/400(12)

=27m/4,800​

The ending balance is then the principle increased by the interest:Ending balance

=p+I

=3m+27m/4,800

=14,400m/4,800+27m/4,800

=14,400m+27m/4,800

=14,427m/4,800

=4,809m/1,600​

Hence,

The ending balance on the last day of the month is 4,809m /1,600.

Therefore,The ending balance on the last day of the month is 4,809m/1,600.
