Suppose you need $50,000 ten years from now. you plan to make seven equal annual deposits with the first deposit to be made three years from today (e.g. t=3) in an account that yields 11% compounded annually. thus, your last deposit will be made at t=9. the money will remain in your account for one more year; it will continue to accrue interest, but you will not make at deposit at t=10. you will, however, withdraw $50,000 at that time. how much should each annual deposit be? (you might want to draw a time line to be sure you understand when the deposits are made.)
