Future value and present value are two key business tools.
Required:
Ignoring income taxes, answer the following independent questions:
A. Your best friend won the state lottery and has offered to give you $15,000 at the end of eight years (after he has made his first million). You figure that if you had the money now, you could invest it at a rate of 10% compound annually. What is the value today of your friend's future gift?
B. Suppose that you invest $11,000 today in an account that bears interest at the rate of 6% compounded annually. What will your investment grow to at the end of seven years?
C. Suppose that your best friend won the state lottery and promised to give you $9,000 per year for five years. The first payment will be made at the end of 20x1. Using a 12% annual compound discount rate, what is the value of these payments at the beginning of 20x1?
D. Suppose that you invest $2,000 at the end of each year for nine years in an investment that provides a return of 8% compounded annually. What will be the value of your investment at the end of nine years?
