Chris is trying to sell his car for $5200 and has gotten two price offers. One buyer offered to pay the full price if Chris would pay for the car maintenance inspection, which cost a tenth of Chris's asking price. The other buyer agreed to pay the price if Chris replaced the headlights for $80 and the tires for three times as much. What is the difference between the amounts Chris will earn from the two offers? Let's answer step by step:
Chris would earn 5200 - 5200 / 10 = 5200 - 520 = $4680 from the first buyer. He would earn 5200 - 80 - 80 * 3 = 5200 - 80 * 4 = 5200 - 320 = $4880 from the second buyer. The difference between Chris's earnings would be 4880 - 4680 = $200. The answer: 200.
