A man is planning to retire in 20 years. Money can be deposited at 6% interest compounded monthly, and it is also estimated that the future general inflation (f overbarf ) rate will be 4% compounded annually. What amount of end-of month deposit must be made each month until the man retires so that he can make annual withdrawals of $60,000 in terms of today's dollars over the 15 years following his retirement? (Assume that his first withdrawal occurs at the end of the first six months after his retirement.)
