A. You're trying to save to buy a new $230,000 Ferrari. You have $40,000 today that can be invested at your bank. The bank pays 5.5 percent annual interest on its accounts. How long will it be before you have enough to buy the car?

B. Your coin collection contains 54 each of 1955 silver dollars. If your grandparents purchased them for their face value when they were new, how much will your collection be worth when you retire in 2055, assuming they appreciate at a 10 percent annual rate?

C. You are scheduled to receive $27,000 in two years. When you receive it, you will invest it for 5 more years at 8.0 percent per year. How much will you have in 7 years?
