Suppose that you have the option to lease a new Mitsubishi Eclipse, which you otherwise intend to buy. You must put $2000 down, and will make payments of $315 per month for 48 months, at the beginning of each month. Upon termination, you can purchase the car for an additional payment of $7000 at lease expiration. Alternatively, the dealer has offered to finance the purchase at 6.6% APR for 48 months, with nothing down, yielding payments of $490 per month at the end of each month. If you choose to purchase the car using dealer financing, rather than choosing the lease-purchase option, how much have you saved (+) or lost (-) on the effective purchase price of the car in dollars and cents. (make your answer positive when you save, negative when you are paying more.)
