Dustin and Christy are saving for their daughter, Ella's, college. They just received an inheritance and want to put some of it into a fund (one lump sum deposit today) that will pay for Ella's college, which will begin in 15 years. Ella's college expenses are estimated to be $75,000 15 years from today, and are expected to grow by 9% per year for the remaining three years. How much money should Dustin and Christy put in the fund today? Assume they can earn 8% on their investment.
