John is planning to take a trip around the world twenty years from
today. In order to pay for this trip he plans to make equal yearly
deposits in years 1-through-11 into an account paying 9% interest
compounded annually. He plans to make five $50,000 yearly
withdrawals from the account with the first withdrawal occurring
twenty years from today. How much must he save each year to provide
himself with the necessary spending money for this dream
vacation?
