He determines that he needs $20,000 per year once he retires, with the first retirement funds withdrawn one year from the day he retires. He estimates that he will earn 11 % per year on the retirement funds and that he will need funds up to and including his 20th birthday after retirement. i. How much he needs to deposit in an account today so that he has enough funds to meet all his future expenditures? ii.
