5. Mateo’s sister paid off her student loan of $5000 in 3 years. If she made a payment of $152.35 each month, what was her simple interest rate for her loan? Round to the nearest hundredth.

SOLUTION: First find the total amount Mateo’s sister will pay. Mateo’s sister made payments of $152.35 each month for 3 years, or 36 months. The total amount she will pay over the length of the loan is 36 • 152.35 = $5484.60. Next, subtract the principal to find out how much interest she paid. 5484 – 5000 = $484. Use the simple interest formula to find the interest rate.

33. Model with Mathematics Give a principal and interest rate where the amount of simple interest earned in four years would be $80. Justify your answer.

In order to earn $80 in four years, the principal investment times the rate must equal 20. One example of this is the principal is $2000 and the rate is 1% or 0.01, since 0.01 • 20000 = 20. Then I = $2000 • 0.01 • 4 or $80.

34. Justify Conclusions Kai-Yo deposits $500 into an account that earns 2% simple interest. Marcos deposits $250 into an account that earns 4% simple interest. How much money does each have after 10 years? Who will have more money over the long run? Explain your reasoning.

SOLUTION: Kai-Yo deposits $500 in an account with 2% simple interest.

Kai-Yo will have 500 + 100 = $600 after 10 years. Marcos deposits $250 in an account with 4% simple interest.

Marcos will have 250 + 100 = $350 after 10 years. Even though Kai-Yo and Marcos earn the same amount of interest after every year, Kai-Yo will always have $250 more than Marcos because that was the difference in the initial deposit.

35. Find the Error Sabino is finding the simple interest on a $2500 investment at a simple interest rate of 5.75% for 18 months. Find his mistake and correct it.

SOLUTION:

Sabino did not convert the time to years.

36. Persevere with Problems Determine the length of time it will take to double a principal of $100 if deposited into anaccount that earns 10% simple annual interest.

SOLUTION: When the principal doubles, the interest earned will be $100.

It will take 10 years for the principal to double.

37. Building on the Essential Question Compare simple and compound interest.

SOLUTION: Sample Answer: With simple interest, the amount of money earned will be the same each year because it is always applied to the initial amount. With compound interest, the amount of interest will increase each year because it is being applied to the new total after the interest is added each year.

38. A $500 certificate of deposit has a simple interest rate of 7.25%. What is the value of the certificate after 8 years?

A $290B $500C $790D $2900

SOLUTION:

The simple interest earned is $290. The value of the certificate will be 500 + 290 = $790 after 8 years. Choice C is the correct answer.

39. Beatriz borrowed $1500 for student loans. She will make 30 equal payments of $62.50 to pay off the loan. What is the simple interest rate for the loan?

F 4%G 7%H 8.5%J 10%

SOLUTION: Beatriz will make 30 equal payments of $62.50 to pay off her loan. The total amount she will pay is 30 • 62.50 = $1875. She will pay 1875 – 1500 = $375 in interest. Her loan is for 30 months, or 2.5 years.

The simple interest rate is 10%. Choice J is the correct answer.

40. A savings account with $2250 has an interest rate of 5%. If the interest is compounded annually, how much will be in the account after 2 years?

A $230.63B $337.50C $2480.63D $2587.50

SOLUTION:

There will be $2480.63 in the account after 2 years. Choice C is the correct answer.

Year Principal Interest Amount at end of year 1 $2250 2250 + 112.50 = $2362.50

2 $2362.50 2362.50 + 118.13 = $2480.63

41. Short Response Which of the following plans will produce the greater earnings for an investment of $500 over 5 years? How much more will that plan earn?

SOLUTION: For plan A, the simple interest rate is 0.0675 for $500 invested over 5 years.

The interest for Plan A is $168.75. For Plan B, the interest is compounded annually.

For plan B the amount of interest earned is 685.04 – 500 = $185.04. Since $185.04 > $168.75, plan B produces the greater investment. Plan B earns $185.04 – $168.75 or $16.29 more than plan A.

1 $500 500 + 32.50 = $532.50

2 $532.50 532.50 + 34.61

= $567.11

3 $567.11 567.11 + 36.86

SOLUTION:

2 $2362.50 2362.50 + 118.13 = $2480.63

1 $500 500 + 32.50 = $532.50

2 $532.50 532.50 + 34.61

= $567.11

3 $567.11 567.11 + 36.86

= $603.97

4 $603.97 603.97 + 39.26

= $643.23
