Your cousin wants to buy a car but he really can't afford it. He needs a loan of $22,000. The finance manager at the dealership offers him something like a loan in which your cousin will get the $22,000 and will pay $413 per month for the next 60 months with an additional payment of $3,000 (which the car will surely be worth!) in the 60th
month. What interest rate is your cousin really going to pay?
