You want to endow a scholarship that will pay $15,000 per year forever, starting one year from now. If the school's endowment discount rate is 6%, what amount must you donate to endow the scholarship? How would your answer change if you endow it now, but it makes the first award to a student 10 years from today? What is the present value of $5,000 paid at the end of each of the next 73 years if the interest rate is 10% per year
