A student organization wanted to set up an endowment that would award seven (7) engineering students scholarships of $20,000 per year forever. The first seven scholarships are to be granted beginning at the end of year 5 and continue forever. How much must the organization donate the first four years (there are four deposits made at the end of year 1, year 2, year 3 and year 4 respectively), if the endowment fund is expected to earn interest at a rate of 12% per year
