1. Last national bank offers a CD paying 7% interest (compounded annually). If you invest \$1,000 how much will you have at the end of year 5.

2. You want to buy a house in 4 years and expect to need \$25,000 for a down payment. If you have \$15,000 to invest, how much interest do you have to earn (compounded annually) to reach your goal?

3. You want to buy your dream car, but you are \$5,000 short. If you could invest your entire savings of \$2,350 at an annual interest of 12%, how long would you have to wait until you have accumulated enough money to buy the car?

4. How much do you have to invest today at an annual rate of 8%, if you need to have \$5,000 six years from today?

6 You are planning your retirement and you come to the conclusion that you need to have saved \$1,250,000 in 30 years.

7. You want to buy a new plasma television in 3 years, when you think prices will have gone down to a more reasonable level. You anticipate that the television will cost you \$2,500. If you can invest your money at 8% compounded monthly, how much do you need to put aside today?

How much money do you have to have in your retirement account to make this happen. Assume that you can earn 8% on your investments.

11. You are offered a security that will pay you \$2,500 at the end of the year forever. If your discount rate is 8%, what is the most you are willing to pay for this security?
