Question

Assume that you have x dollars saved (you choose a specific dollar amount) and would like to purchase a used car in two years. Calculate the interest earned over the two-year span on your chosen dollar amount at the 5.50% interest rate, compounded daily, for a one year CD. Show your work. Calculate how much you will have saved with this account in two years. Show your work. Investigate bank interest rates available in your area for a one year CD. Calculate how much money you will have in two years if the interest is compounded monthly or continuously. Show your work. How did the change in rates affect your purchasing power?

Explanation / Answer

Amount = Principal * (1+ interest rate)^number of period

The change in rates has a huge impact on the purchasing power. Suppose if the inflation rate is high it will reduce the purchasing power and vice versa.
