#### Homework Answers

Answer #1

1.Information provided:

Future value= \$500,000

Time= 20 years

Required rate of return= 8%

The question is solved by computing the present value.

Enter the below in a financial calculator to compute the present value:

FV= 500,000

N= 20

I/Y= 8

Press the CPT key and PV to compute the present value.

The value obtained is 107,274.10.

Therefore, Sara must deposit \$107,274 to have \$500,000 in 20 years.

Hence, the answer is option 4.

2.Information provided:

Face value= \$25,000

Present value = \$10,000

Time= 10 years

Enter the below in a financial calculator to calculate the interest rate:

FV= 25,000

PV= -10,000

N= 10

Press the CPT key and I/Y to compute the interest rate.

The value obtained is 9.5958.

Therefore, the interest rate is 9.6%.

Hence, the answer is option b.
