Suppose that you decide to buy a car for $63,000, including taxes and license fees. You saved $ 13,000 for a down payment. The dealer is offering you a choice between two incentives. Incentive A is $7000 off the price of the car, followed by a five-year loan at 7.69%. Incentive B does not have a cash rebate, but provides free financing (no interest) over five years.
