Q: Jordan decides to start an exercise program when he weighs 250 pounds. For the first 4 weeks, he loses 3 pounds a week. After that, he loses 2 pounds a week for 8 weeks. How much does Jordan now weigh?
A: He loses 3 pounds a week for 4 weeks for a total of 3 * 4 = 12 pounds. He loses 2 pounds a week for 8 weeks for a total of 2 * 8 = 16 pounds. All total he has lost 12 + 16 = 28 pounds. Jordan weighed 250 pounds and has lost 28 pounds so he now weighs 250 - 28 = 222 pounds. The answer is 222.
Question: Jenine can sharpen a pencil 5 times before it runs out. She needs to sharpen a pencil for every 1.5 hours of use. She already has ten pencils and needs to write for 105 hours. A new pencil costs $2. How much does she need to spend on more pencils to be able to write for 105 hours?
Answer: A pencil last 7.5 hours because 5 x 1.5 = 7.5. The pencils she has will last 75 hours because 10 x 7.5 = 75. She needs 30 more hours of writing because 105 - 75 = 30. She will need 4 more pencils to reach this because 30 / 7.5 = 4. She will spend $8 on pencils because 4 x 2 = 8. The answer is 8.
[Question]Lola and Tara decide to race to the top of a 20 story building. Tara takes the elevator and Lola runs up the stairs. Lola can run up 1 story in 10 seconds. The elevator goes up a story in 8 seconds but stops for 3 seconds on every single floor. How long would it take for the slower one of Lola and Tara to reach the top floor?
[Answer]Lola climbs 20 stories in 20 stories x 10 seconds / story = 200 seconds. Tara can go up the elevator in 8 seconds / story x 20 stories = 160 seconds without the stops at each floor. The elevator stops for 3 seconds on each floor for a total of 20 stories x 3 seconds / story = 60 seconds. In total it takes Tara 160 seconds + 60 seconds = 220 seconds to reach the top floor. Because 200 < 220 Lola wins. The answer is 220.

Question: A carton contains 12 boxes. If each box has 10 packs of cheese cookies, what's the price of a pack of cheese cookies if a dozen cartons cost $1440?
Answer: If 1 carton contains 12 boxes, then a dozen cartons contain 12 * 12 = 144 boxes. If 1 box has 10 packs of cookies, then 144 boxes have 144 * 10 = 1440 packs. If a dozen cartons cost $1440 and contain 1440 packs of cookies, then each pack costs 1440 / 1440 = $1. The answer is 1.
