A plantiff in successful lawsuit was awarded a judgement of $5500 per month for 5 years. The plantiff has the need of a fairly large sum of money immediately for an investment of his own, and has offered the defendant the opportunity to pay of the award in a lump-sum amount of $110,000. If the defendant accepts the offer and pays the $110,000 now, what rate of return will the defendant have made by not paying the 60 monthly amounts?
