Suppose that your friends are saving for their sons college tuition. They estimate that tuition costs will be $25,000 per semester when their son starts college 10 years from now. They further estimate that tuition costs will increase by 1% per semester while their son is in college. They need to be able to withdraw money for tuition at the beginning of each semester for the 8 semesters of their sons college career. To do this, they plan to deposit money at the end of each month (starting one month from today) until the date of their last tuition withdrawal. If their investment account earns 8% compounded semiannually, how much money do they need to deposit each month in order to meet their college savings goal?
