You just won a lottery and your parents have always told you to plan for the future so since you

already have a well-paying job you decide to invest rather than spend your lottery winnings. The payment schedule from

the lottery commission is $100000 after taxes at end of year one and 19 more payments of exactly $100000 after taxes in

equal annual end-of-the-year deposits (i.e. the first of the next 19 deposits is one year from today) into your account

paying 7% compounded annually. How much money will be in your account after the last deposit is made?
