Answer:
Maya spends $22,500 in those 5 year and Darrel spent $22,000 in all. So, Maya spent more than Darrel by $500. If Darrel were to sell his car, he would have gained $8,500 and then have $13,500 gained from after the car payment, but after getting a new one, he would have spent $35,000. So, I think Maya would be better off. (I don't really know the meaning, sorry if it's wrong.)
