Q: Team Soccer Stars plays in a soccer league. They played a total of 20 games, and won 14 games, lost 2, and drew the rest of the matches. They earn 3 points for a win, 1 point for a draw, and nothing for a loss. How many points did they have at the end of the season?
A: Soccer Stars won and lost a total of 14 + 2 = 16 games. This means they drew 20 - 16 = 4 games. The total points from the wins are 14 * 3 = 42 points. The total points from draws are 4 * 1 = 4 points. The total points from the losses are 2 * 0 = 0 points. They had 42 + 4 + 0 = 46 points when the season ended. The answer is 46.
Question: John has 3 bedroom doors and two outside doors to replace. The outside doors cost $20 each to replace and the bedroom doors are half that cost. How much does he pay in total?

Q: 10 boxes each contain 50 bottles of water. Each bottle has a capacity of 12 liters and is filled up to 3/4 of its capacity. How many liters of water altogether are contained within the bottles in the boxes?
A: Since each water bottle has a capacity of 12 liters, when filled up to 3 / 4 of capacity, each carries 3 / 4 * 12 = 9 liters of water. If there are 50 bottles of water in each box, the number of liters the water bottles in a box are carrying is 50 * 9 = 450 liters. In 10 boxes containing bottled water, the total number of liters in the water bottles is 450 * 10 = 4500 liters. The answer is 4500.
Question: Rodney, Roger and Ron can lift a combined weight of 239 pounds. Rodney can lift twice as much as Roger, and Roger can lift 7 pounds less than 4 times the amount that Ron can lift. How much can Rodney lift?
Answer:
Let x represent the amount that Ron can lift. Roger: 4x - 7. Rodney:2(4x - 7) = 8x - 14. Total:x + 4x - 7 + 8x - 14 = 239. 13x - 21 = 239. 13x = 260. x = 20. Rodney:8(20) - 14 = 146 pounds. The answer is 146.
