You have your choice of two investment accounts. Investment A is a 12-year annuity that features end-of-month $1,900 payments and has an APR of 8.3 percent compounded monthly. Investment B is a lump-sum investment with an interest rate of 7.8 percent compounded continuously, also good for 12 years. How much money would you need to invest in Investment B today for it to be worth as much as Investment A 12 years from now?
