You want to start saving for your daughter's college education now. She will enter college at age 18 (when she turns 18, i.e. beginning of 18, end of 17) and will pay fees of $4,000 at the end of each of the four years (fees are paid at the end of 18, 19, 20, 21). You will start your savings by making a deposit in one year and at the end of every year until she begins college. If annual deposits of $2,458.79 (from today onward, at the end of each year) will allow you to reach your goal, how old is your daughter now? Assume you can earn 6% annual interest on your savings. Just turned 13 Just turned 12 Just turned 15
