1. Your coin collection contains 50 1952 silver dollars. If your grandparents purchased them for their face value ($1*50 = $50) when they were new in 1952, how much will your collection be worth when you retire in 2070, assuming they appreciate at an annual rate of 7 percent?

2 . You invest $4,000 today. You hope that the account will grow to be worth $24,000 in 24 years. What rate of return would you require to grow the investment from $4,000 to $24,000 in 24 years?

3. You are scheduled to receive $20,000 in 5 years from today. When you receive the money, you will invest it for 10 additional years at 8% a year. How much will the investment be worth in 15 years from today? Assuming the same discount rate, what is the value of this investment today?

4. I claim I can triple your investment in a year. What quarterly rate of return am I advertising?

5. Show that FV = PV(1+r)t is the same as r = (FV/PV)1/t 1 and t = ln(FV/PV) / ln(1+r).
