At the end of 10 years at 5% discount rate = 15,347.83 and 7 years +12,708.73 discount rate where PV= present value 25,000.00 FV= Future value in time period n= number of years 10 i= interest rate (discount).

4-4.  Suppose you deposit $100 in a savings account that compounds annually at 2%.  After 1 year at this rate, the bank changes its rate of compounding to 1.5% annually.  Assuming the compounding rate does not change for 4 additional years, how much will your account be worth at the end of 5-year period? Answer: Fvn = PV (1 + i)n

                                                                       FV Year =  100 = 110.00
