Question: John repairs 5 cars. 3 of the cars take 40 minutes each to repair. The remaining ones take 50% longer each to repair. He makes $20 per hour repairing cars. How much money does he make?
Answer: The 3 cars take 3 * 40 = 120 minutes to make. He repairs 5 - 3 = 2 more cars. They each take 40 * .5 = 20 minutes longer per car. So they each take 40 + 20 = 60 minutes. So he repaired cars for 120 + 2 * 60 = 240 minutes. That is 240 / 60 = 4 hours. So he made 4 * 20 = $80. The answer is 80.
[Question]The Dark Lord needs to transport 1200 pounds of swords to the Enchanted Forest for a battle with the elves. He has 10 squads of 8 orcs each. How many pounds of swords does each orc have to carry?
[Answer]First find how many orcs there are total by multiplying the number of orcs per squad by the number of squads: 8 orcs / squad * 10 squads = 80 orcs. Then divide the total amount of swords by the number of orcs to find the amount of swords per orc: 1200 pounds / 80 orcs = 15 pounds / orc. The answer is 15.
Q: To make a living, Carl needs to drive a car for 2 hours every day. After he got promoted he needs to drive for 6 more hours every week. How many hours will Carl drive in two weeks?
A: Every week Carl needs to drive additional 6 hours, so in two weeks that would make 2 * 6 = 12 additional hours. Two weeks of driving 2 hours every day, means 14 * 2 = 28 hours of driving. So during two weeks, Carl will drive 28 + 12 = 40 hours. The answer is 40.
Question: Chandra is going on a monster hunt. After a big storm, there have been lost monsters all around the castle grounds for the last 5 days. Chandra wants to rope them all up and return them to the swamps where they will be the most comfortable. On the first day she saw 2 monsters near the castle walls. Every day after that she saw double the amount as the day before. After 5 days how many monsters does she need to lead back to the swamps?
Answer: On the first day Chandra saw 2 monsters and on day 2 she saw twice that amount, 2 x 2 = 4 monsters seen on day 2. On day 3 she saw double that amount of monsters, 4 x 2 = 8. On day 4 she saw double that amount of monsters, 8 x 2 = 16. On day 5 she saw double that amount of monsters, 16 x 2 = 32. Altogether Chandra saw 2 + 4 + 8 + 16 + 32 lost monsters = 62 total lost monsters that Chandra needs to lead back to the swamps. The answer is 62.
[Question]Tanesha needs to buy rope so cut into 10 pieces that are each six inches long. She sees a 6-foot length of rope that cost $5 and also sees 1-foot lengths of rope that cost $1.25 each. What is the least she has to spend to get the rope she needs?
[Answer]She needs 60 inches of rope because 10 x 6 equals 60. The six - foot length of rope is 72 inches long because 6 x 12 = 72. The six - foot length of rope would give her 12 pieces because 72 / 6 = 12. The six - foot length is long enough because 12 > 10. Each 1 - foot rope equals 12 inches. She would need 5 of the 1 - foot ropes because 60 / 12 = 5. If she bought one - foot ropes it would cost $6.25 because 5 x 1.25 = 6.25. The cheapest rope to buy is the 6 - foot rope because 5 < 6.25. The answer is 5.
