SALMAN is 50 years old and recently retired. He wishes to provide retirement income for himself and is considering an annuity contract with the STATE LIFE INSURANCE CO. Such a contract pays him an equal-dollar amount each year that he lives. For this cash-ow stream, he must put up a specic amount of money at the beginning. According to actuary tables, his life expectancy is 25 years, and that is the duration on which the insurance company bases its calculations regardless of how long he actually lives.

A. If Salman Life uses a compound annual interest rate of 8 percent in its calculations,

what must Cohen pay at the outset for an annuity to provide him with $50,000 per year? (Assume that the expected annual payments are at the end of each of the 15 years.)

B. What would be the purchase price if the compound annual interest rate is 12 percent?

C. Salman had $90,000 to put into an annuity. How much would he receive each year if the insurance company uses a 5 percent compound annual interest rate in its calcula- tions? A 10 percent compound annual interest rate?

D. Salman had $90,000 to put into an annuity. How much would he receive each year if 10 percent compound annual interest rate?
