(Compound interest with nonannual periods) a. Calculate the future sum of $ 5,000, given that it will be held in the bank for 10 years at an APR of 66 percent. b. Recalculate part (a) using compounding periods that are (1) semiannual and (2) bimonthly (every two months). c. Recalculate parts (a) and (b) for an APR of 12 percent. d. Recalculate part (a) using a time horizon of 20 years? (the APR is still 66 percent). e. With respect to the effect of changes in the stated interest rate and holding periods on future sums in parts (c) and (d), what conclusions do you draw when you compare these figures with the answers found in parts (a) and (b)?
