You have your choice of two investment accounts. Investment A is a 13-year annuity that features end-of-month $1,600 payments and has an APR of 7.8 percent compounded monthly. Investment B is an annually compounded lump-sum investment with an interest rate of 9 percent, also good for 13 years. How much money would you need to invest in B today for it to be worth as much as Investment A 13 years from now?
