you are saving for the college education of two children. one child will enter college in 5 years, while the other child will enter college 2 years later in 7 years. college costs are currently $10,000 per year and are expected to grow at a rate of 2% per year. you assume that each child will be in college for four years. therefore you will be paying tuition for 6 years before both children graduate. you currently have $30,000 in your educational fund. your plan is to contribute a fixed amount to the fund over each of the next 5 years. your first contribution will come at the end of this year, and your final contribution will come at the date when you make the first tuition payment for your oldest child in year 5. you expect to invest your contributions into various investments, which are expected to earn 5% per year the same rate of interest as today. how much should you contribute in each of the next 5 years in order to have enough money at year 5 which if reinvested at 5% will meet the expected yearly cost of your childrens education?
