You want to setup a trust today that will pay out scholarships for the less fortunate. You want the trust to pay out $100,000 in scholarships 30 years from today. You want this amount to increase 4% per year and go on forever. If your trust can earn 10% returns, how much do you need to put in the trust today?

If possible, please show a step by step explanation, I'm having a very difficult time understanding they why behind this question. Thank you!
