Introduction:

The annual rate that is earned from the investment or charged for a borrowing is an annual percentage rate and it is also represented as APR. Thus, the APR is calculated by multiplying the rate of interest for a year with the number of months in a year. The effective annual rate is the rate of interest that is expressed as if it were compounded once in a year.

Expert Solution

Answer to Problem 77QP

The annual percentage rate is 390%, the effective annual rate is 4,197.74%

Explanation of Solution

Given information:

A check-cashing store makes a personal loan to wake-up consumers. The store offers a week loan at the rate of interest of 7.5% per week. Then, after few days, the store again makes a one-week loan at a discount interest rate of 7.5% for a week. The store also makes an add-on interest on the loan at a discount interest rate of 7.5% for a week.

Thus, if Person X borrows $100 for 4 weeks, the interest would be $33.55. As this is a discount interest rate, the net proceeding of Person X will be $66.45. Thus, Person X has to pay $100 for a month and the store also lets Person X to pay $25 in installments for a week.

Compute the annual percentage rate:

APR=52(7.5%)=390%

Note: The annual percentage rate is computed by multiplying the interest rate with the number of months in a year. Here, the interest is calculated per week and so the number of weeks in a year (52 weeks) is taken as the period.

Hence, the annual percentage rate is 390%

Formula to calculate the effective annual rate:

Effective annual rate=(1+(APR12)12−1)

Compute the effective annual rate:

Effective annual rate=(1+(APR12)12−1)=(1+0.075)52−1=42.9774−1=41.9774

Hence, the effective annual rate is 0.41,9774 or 4,197.74%

Answer to Problem 77QP

The annual percentage rate is 421.62%, the effective annual rate is 5,662.75%

Explanation of Solution

Given information:

A check-cashing store makes a personal loan to wake-up consumers. The store offers a week loan at the rate of interest of 7.5% per week. Then, after few days, the store again makes a one-week loan at a discount interest rate of 7.5% for a week. The store also makes an add-on interest on the loan at a discount interest rate of 7.5% for a week.

Thus, if Person X borrows $100 for 4 weeks, the interest would be $33.55. As this is a discount interest rate, the net proceeding of Person X will be $66.45. Thus, Person X has to pay $100 for a month and the store also lets Person X to pay $25 in installments for a week.

Explanation:

In the discount loan, the amount that Person X gets is reduced by the discount and Person X has to pay back the full principal value. With the discount of 7.5%, Person X receives $9.25 for each $10 as the principal value. The weekly interest rates are calculated as follows:

$10=$9.25(1+r)r=($10$9.25)−1r=1.0811−1r=0.0811

Note: The dollar values that are used above are not relevant. In other words, it can also be written as $0.925 and $1 or $92.5 and $100 or in any other combination that provides similar rate of interest.

Hence, the r value is 0.0811 or 8.11%

Compute the annual percentage rate:

APR=52(8.11%)=421.62%

Note: The annual percentage rate is computed by multiplying the interest rate with the number of months in a year. Here, the interest is calculated per week and so the number of weeks in a year (52 weeks) is taken as the period.

Hence, the annual percentage rate is 421.62%

Formula to calculate the effective annual rate:

Effective annual rate=(1+(APR12)12−1)

Compute the effective annual rate:

Effective annual rate=(1+(APR12)12−1)=(1+0.0811)52−1=57.6275−1=56.6275

Hence, the effective annual rate is 56.6275 or 5,662.75%

Thus, if Person X borrows $100 for 4 weeks, the interest would be $33.55. As this is a discount interest rate, the net proceeding of Person X will be $66.45. Thus, Person X has to pay $100 for a month and the store also lets Person X to pay $25 in installments for a week.

Compute the annual percentage rate:

APR=52(7.5%)=390%

Note: The annual percentage rate is computed by multiplying the interest rate with the number of months in a year. Here, the interest is calculated per week and so the number of weeks in a year (52 weeks) is taken as the period.

Hence, the annual percentage rate is 390%

Formula to calculate the effective annual rate:

Effective annual rate=(1+(APR12)12−1)

Compute the effective annual rate:

Effective annual rate=(1+(APR12)12−1)=(1+0.075)52−1=42.9774−1=41.9774

Hence, the effective annual rate is 0.41,9774 or 4,197.74%

Answer to Problem 77QP

The annual percentage rate is 421.62%, the effective annual rate is 5,662.75%

Explanation of Solution

Given information:

A check-cashing store makes a personal loan to wake-up consumers. The store offers a week loan at the rate of interest of 7.5% per week. Then, after few days, the store again makes a one-week loan at a discount interest rate of 7.5% for a week. The store also makes an add-on interest on the loan at a discount interest rate of 7.5% for a week.

Thus, if Person X borrows $100 for 4 weeks, the interest would be $33.55. As this is a discount interest rate, the net proceeding of Person X will be $66.45. Thus, Person X has to pay $100 for a month and the store also lets Person X to pay $25 in installments for a week.

Explanation:

In the discount loan, the amount that Person X gets is reduced by the discount and Person X has to pay back the full principal value. With the discount of 7.5%, Person X receives $9.25 for each $10 as the principal value. The weekly interest rates are calculated as follows:

$10=$9.25(1+r)r=($10$9.25)−1r=1.0811−1r=0.0811

Note: The dollar values that are used above are not relevant. In other words, it can also be written as $0.925 and $1 or $92.5 and $100 or in any other combination that provides similar rate of interest.

Hence, the r value is 0.0811 or 8.11%

Compute the annual percentage rate:

APR=52(8.11%)=421.62%

Note: The annual percentage rate is computed by multiplying the interest rate with the number of months in a year. Here, the interest is calculated per week and so the number of weeks in a year (52 weeks) is taken as the period.

Hence, the annual percentage rate is 421.62%

Formula to calculate the effective annual rate:

Effective annual rate=(1+(APR12)12−1)

Compute the effective annual rate:

Effective annual rate=(1+(APR12)12−1)=(1+0.0811)52−1=57.6275−1=56.6275

Hence, the effective annual rate is 56.6275 or 5,662.75%

Hence, the r value is 18.62%

Compute the annual percentage rate:

APR=52(18.62%)=968.19%

Note: The annual percentage rate is computed by multiplying the interest rate with the number of periods in a year. Here, the interest is calculated per week and so the number of weeks in a year (52 weeks) is taken as the period.

Hence, the annual percentage rate is 968.19%

Formula to calculate the effective annual rate:

Effective annual rate=(1+(APR12)12−1)

Compute the effective annual rate:

Effective annual rate=(1+(APR12)12−1)=(1+0.1862)52−1=7,178.4521−1=7,177.4521

Hence, the effective annual rate is 7,177.4521 or 717,745.21%.

Summary Introduction

To calculate: The annual percentage rate and the effective annual rate

Introduction:

The annual rate that is earned from the investment or charged for a borrowing is an annual percentage rate and it is also represented as APR. Thus, the APR is calculated by multiplying the rate of interest for a year with the number of months in a year. The effective annual rate is the rate of interest that is expressed as if it were compounded once in a year.

Explanation of Solution

Given information:

A check-cashing store makes a personal loan to wake-up consumers. The store offers a week loan at the rate of interest of 7.5% per week. Then, after few days, the store again makes a one-week loan at a discount interest rate of 7.5% for a week. The store also makes an add-on interest on the loan at a discount interest rate of 7.5% for a week.

Thus, if Person X borrows $100 for 4 weeks, the interest would be $33.55. As this is a discount interest rate, the net proceeding of Person X will be $66.45. Thus, Person X has to pay $100 for a month and the store also lets Person X to pay $25 in installments for a week.

Explanation:

In this part, the present value of an annuity and the cash flow is given; with the help of the present value of annuity equation, the r value is found using a spreadsheet.

Formula to calculate the present value annuity:

Present value annuity=C{[1−(11+rt)]r}

Note: C denotes the payments, r denotes the rate of exchange, and t denotes the period. Using the formulae of the present value of annuity, the interest rate is computed using the spreadsheet method.

Compute the present value annuity:

Present value annuity=C{[1−(1(1+r)t)]r}$66.45=$25{[1−(1(1+r)4)]r}
