You plan to start saving for your son's college education. He will begin college when he turns eighteen and will need $4,000 then and in each of the following three years.
You will make a deposit at the end of this year in an account that pays 6 percent compounded annually and an identical deposit at the end of each year, with the last deposit occurring when he turns eighteen.
If an annual deposit of $1,484 will allow you to reach your goal, how old is your son now?
