Linus has just won the "Wait To Spend" lottery. Specifically Linus has won the lump sum amount of $2650 but he must wait until the end of 6 years to receive the money. Linus is in need of cash and would rather receive a different pattern of payments: $325 today and then receive some unknown LUMP SUM (i.e. one time) amount that will be received in 6 years. Using an interest rate of 8.50%, determine the unknown lump sum amount that would make the present value of both prizes equivalent.
