Q: Alfonso earns $6 each day walking his aunt’s dog. He is saving to buy a mountain bike helmet for $340. Currently, he already has $40. If he walks his aunt's dog 5 days a week, in how many weeks should Alfonso work to buy his mountain bike?
A: Alfonso has to work for the $340 - $40 = $300. In a week, he earns $6 x 5 = $30. Thus, he needs to work $300 / $30 = 10 weeks to buy the bike. The answer is 10.
Question: James wants to learn to become a chess grandmaster. It takes 2 hours to learn the rules. It then takes him 49 times that long to get a level of proficiency to start playing in local tournaments. After that, he devotes his life to chess and spends 100 times as much as the combined time to get proficient to becoming a master. How much total time did he spend?
Answer: It takes him 2 * 49 = 98 hours to go from knowing how to play to proficient. So he spends 98 + 2 = 100 hours combined on those. So it takes him 100 * 100 = 10,000 hours to become a master from proficient. So the total time was 100 + 10000 = 10,100 hours. The answer is 10100.

Q: Harry's birthday was three weeks after the closing of the school. His three friends decided to contribute an equal amount of money to throw him a party. Harry added $30 to the contribution, making the total contribution three times as much as Harry contributed. Calculate the total amount of money that each of Harry's friends contributed.
A: If the total contribution was three times as much as Harry contributed, and Harry contributed $30, the total contribution was 3 * $30 = $90. Since Harry contributed $30, his three friends together contributed $90 - $30 = $60. Since the three friends were contributing an equal amount, each friend contributed $60 / 3 = $20. The answer is 20.
Question: A jug needs 40 cups of water to be full. A custodian at Truman Elementary School has to fill water jugs for 200 students, who drink 10 cups of water in a day. How many water jugs will the custodian fill with cups of water to provide the students with all the water they need in a day?
Answer:
Since each student needs 10 cups of water per day and there are 200 students, the custodian has to provide 200 * 10 = 2000 cups of water. A jug of water needs 40 cups to be full, so 2000 cups of water will fill 2000 / 40 = 50 jugs. The answer is 50.
