We have done most of our work this semester with Excel and a financial calculator. We do need to grasp a basic algebraic formula that relates to the time value of money. Which of the following is the correct formula for the present value of an investment that has a future value of $200, six years out using a 4% interest rate? a. O b. O c. PV = $200/((1 + .04) x 6) O d. PV = $200 / (1+.06)^4 PV = $200 / (1+.04)^6 PV = $200/(.04 x 6)
