You have your choice of two investment accounts. Investment A is a 13-year annuity that features end-of-month $1,800 payments and has an APR of 8.1 percent compounded monthly. Investment B is a 7.6 percent continuously compounded lump sum investment, also good for 13 years. How much money would you need to invest in Investment B today for it to be worth as much as Investment A 13 years from now?
