Camilla's son starts college in 17 years. She estimates that the current value of college education funds required for her son's education is $74,263. Assume that after-tax annual rate of return that Camilla is able to earn from her investment is 3.78 percent compounded monthly. She is going to invest equal amounts every month at the beginning of the period until her son starts college. Compute the monthly beginning of-the-period payment that is necessary to fund the current value of college education costs. (Please use monthly compounding, not simplifying average calculations)
