You just won $4,200,000 at a casino slot machine. The owners congratulate you and ask you to sign a contract where they pay you the $4,200,000 in an immediate payment today of $200,000 plus 20 equal installments of $200,000 paid at the end of each of the next 12 months (i.e. in 12 months you get a cheque, 12 months later you get another cheque, and on until 20 years is over). Use an interest rate of 3.25%.
