You are a very generous person. You are willing to set apart half of your salary during the next 10 years and put it in a trust fund that will earn an annual interest rate of 5%. After those 10 years you won't deposit anything else, but you are going to keep that money in the trust fund. Your intention is that after you die, the money in the trust fund will be used to give each year a scholarship of $150,000 to the best student in your home town to pay for his/her college. If you expect to die in 50 years from now, and you want this fund to continue indefinitely, how much does your annual salary needs to be to make this possible? Include cash flow diagram.
