A bank pays interest at an annual rate of 4%. An investor deposits $10000 at time zero, deposits $3000 one year later and withdraws $5000 after one more year (time 2). What is the investor's balance at time 2 (assuming no further transactions)? Another investor makes the same deposits and withdrawal into and from a mutual (stock market) fund. His balance after three years is $9500. Set up an equation whose solution would give i, the (annual) internal rate of return. Use your calculator to find i - the annual interest rate. Explain how you entered data in the calculator, e.g. what are PV, PMT, FV? If you used a graphing calculator explain your entries
