Lets say that you have a friend who is 24 years old and she is having her first child (Congratulations!!!!). She wants to make sure that her child will have enough money for college so she is considering prepaid college plans and investment. How much money would she have to invest monthly (assuming monthly compounding) in order to ensure that there is $250,000 in an account for her child in 18 years. She forecasts that she will receive a 7% annual rate of return on the money she invests consistently for the full 18 years. (use two decimal places in your answer)
