Calculating present values
A 5-year annuity of 10 $7,800 semiannual payments will begin 9 years from now, with the first payment coming 9.5 years from now. If the discount rate is 9 percent compounded semiannually, what is the value of this annuity five years from now? What is the value three years from now? What is the present value of the annuity?
