1. As stated in the chapter, annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). However, an exception occurs when the annuity payments come in the beginning of each period (termed an annuity due). To find the present value of an annuity due, subtract 1 from n an add 1 to the tabular value. For example, to find the future future percent, go to Appendix C for n = 6 and i = 10 percent. Look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or \$671.60 (\$100 x 6.716).

What is the future value of a 10-year annuity of \$2,000 per period where payments come at the beginning of each period? The interest rate is 8 percent.

2. Related to the discussion in problem 23, what is the percent value of a 10-year annuity of \$3,000 per period in which payments come at the beginning of each period? The interest rate is 12 percent.

3. You need \$23,956 at the end of nine year, and your only investment outlet is a 7 percent long-term certificate of deposit (compounded annually). With the certificate of deposit, you make an initial investment at the beginning of the first year.

5. On January 1, 2005, Mr. Dow bought 100 shares of stock at \$12 per share. On December 31, 2008, he sold the stock for \$18 per share. What is his annual rate on return? Interpolate to find the answer.
