During the first 3 years, interest is credited using a compound interest rate of 4% per year. After 3 years, interest is credited at a force of interest: S _ 0.1 dt = 11017,t> 3 An The following are numerically equal the current value at time t = 3 of payment of 1000 at time t = 2 and 500 at time t = 6; and the present value at time t = 0 of a payment of X at time t = 10. Calculate X During the first 3 years, interest is credited using a compound interest rate of 4% per year.
