Question: Hayden has a tank with a small hole in the bottom. The tank starts with 40 gallons of water. It loses 2 gallons of water per hour. Hayden does not add any water for the first two hours. He adds 1 gallon of water to the tank in hour three. He adds three gallons of water to the tank in the fourth hour. How much water is left in the tank at the end of the fourth hour?

A: Britney has 11 * 2 = 22 Rhode Island Reds. She has 6 / 2 = 3 Golden Comets. She has 22 + 3 = 25 total. Susie has 11 + 6 = 17 total. Britney has 25 - 17 = 8 more. The answer is 8.
Question: 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?
Answer: 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 is 200.
