Compound Interest
5-1B. (Compound interest) To what amount will the following investments accumulate?
a. $4,000 invested for 11 years at 9 percent compounded annually
FV = PV(1 + r)n where PV is the present value
FV is the future value
r is the discount rate
n is the period
FV = 4,000(1 + 0.09)11
FV = 10,321.71

b. $8,000 invested for 10 years at 8 percent compounded annually

Then you can replace the information into the formula to find the answer.

FV = 17,271.40

c. ...
