### Compute the present value of a $100 cash flow for the following combinations of discount rates and times Compute the future value of a $100 cash flow for the same combinations of rates and times as in problem 1 How long will it take for $400 to grow to $1,000 at the interest rate specified What is the present value of a 3-year annuity of $100 if the discount rate is 6 percent What is the present value of the annuity in (a) if you have to wait 2 years instead of 1 year for the payment stream to start?

Present Values. Compute the present value of a $100 cash flow for the following combinations of discount rates and times: r = 8 percent. t = 10 years. r = 8 percent. t = 20 years. r = 4 percent. t = 10 years. r = 4 percent. t = 20 years. Future Values. Compute the future value of a $100 cash flow for the same combinatio
