The relationship between the value of an annuity and the level of interest rates is as follows: The present value of an annuity as r rises; the future value of an annuity as r rises. Suppose you just bought a 15-year annuity of $9,000 per year at the current interest rate of 10 percent per year. The present value of this investment is $. If interest rates suddenly rise to 15 percent, the present value of your investment to $. If, instead, interest rates suddenly drop to 5 percent, the present value of your investment to $. (Do not include the dollar signs ($). Round your answers to 2 decimal places. (e.g., 32.16))
