Mr. Henry has come to you for advice on his retirement planning. He is 45 years old and has $ 100,000 in his savings account. He also expects to receive an additional $80,000, after taxes, in ten years, when he sells his house. He plans to work for 20 years more and expects to save $ 10,000 a year for the next 10 years, and $ 15,000 a year for the following 10 years. Assuming that he earns 5% on both his current and future savings, how much should he expect to have in savings, when he retires in 20 years?
