7-10 $58,000

BASIC 1. Present Values. Compute the present value of a $100 cash flow for the following combinations of discount rates and times: *a. r = 8 percent, f= 10 years b. = 8 percent, = 20 years c. r= 4 percent, 1= 10 years d. r=4 percent, 1= 20 years *2. Future Values. Compute the future value of a $100 cash flow for the same combinations of rates and times as in problem 1. 3. Future Values. You deposit $1,000 into your bank account. If the bank pays 4 percent simple interest, how much will you accumulate in your account after 10 years?
