Beginning 1 month from today David B. will deposit each month $200 into an account paying 6% nominal interest. He will make a total of 240 deposits (20 years). After the last deposit the money in the account will begin to earn 4% interest compounded annually. After another 10 years David will begin to withdraw annual amounts for a total of 10 years.
