You plan to start grad school in 5 years and will graduate 5 years after you start. Most of the programs that you are looking at have a tuition payment plan that requires incremental payments of $49,442 per month, due at the beginning of each month. If you start saving, in equal incremental amounts, at the beginning of this month (today) and make your last savings payment one month before you start school, how much must you deposit at the beginning of each month to cover the tuition payments? Assume an interest rate of 9.39% per year.

The answer given was 30,973.37 but how do I get there? Thank you!
