1.(Future value of a complex annuity) Mogul Mr. Smith, age 80, wants to retire at age 100 . Once Mr. Smith retires, he wants to withdraw 1.2 billion at the beginning of each year for 8 years from an account paying 26% annually. To fund his retirement he will make 20 equal end of year deposits into this account that is paying 26% annually. How much will Mr. Smith need at age 100?, and how large of an annual deposit must he make to fund this retirement account?

Example question had age 90 wanting to retire at age 100, wanting to withdraw 1.2 billion for 9 years making 10 equal payments into an account paying 26% annually.
