You are in the process of purchasing a new automobile that will cost you $25,000. The dealership is offering you either a $1,000 rebate (applied toward the purchase price, so that the net purchase price becomes $24,000) if you pay today or 3.9% APR financing for 4 months and no rebate (with each payment made at the end of the month). You have been pre-approved for an auto loan through your local credit union at an interest rate of 7.5% APR for 4 months this would allow you to pay the dealer- ship today and get the $1000 rebate. Which option has the higher monthly payment - financing through your credit union at 7.5% APR and getting the $1000 rebate OR skipping the rebate and fi- nancing the full $25,000 through the dealership at the lower 3.9% APR
