Formula problem: Suppose you invest in a security that increases its return based on length of time held up to 30 years at which time it must be redeemed. You purchase the security for $25,000 today at a 4.8% annual rate that is compounded semiannually for 10 years. After 10 years the interest rate increases to a 6% rate compounded quarterly for the next 10 years. For the final 10 years, the rate goes up to 9% compounded monthly. What would your investment be worth at the end of the 30 years
