John Wick is 50 years old and has saved nothing for retirement. However, he has just inherited 150,000 from his great grandfather and wants to invest it in a retirement plan. He plans to put the money in an investment account earning a 10% return. He will let the money accumulate for 15 years, when he will retire at the age of 65. He would like to deposit enough money so that he can begin making withdrawals of 40,000 per year starting at age 66 and continuing for 24 additional years, when he turns 90. He warns the balance in his account after the last withdrawal to be 0. After investing in his retirement plan, John wants to spend the rest of his money on a world tour.
