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: 10
Step-by-step reasoning process: 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.


Q: Jacob is making s'mores. Each s'more takes two graham crackers and one marshmallow. If Jacob has 48 graham crackers and 6 marshmallows, how many more marshmallows does he need to buy?
A: 18
Step-by-step reasoning process: First find the number of marshmallows Jacob needs: 48 graham crackers / 2 graham crackers / marshmallow = 24 marshmallows. Then subtract the number of marshmallows Jacob already has from the number he needs to find the number he needs to buy: 24 marshmallows - 6 marshmallows = 18 marshmallows.


Q: Hallie borrows a book from the library. She reads the entire book in four days. She read 63 pages the first day. On the second day, she read twice the number of pages that she'd read on day one. On the third day, she read 10 mores pages than she read on day two. If the book is 354 pages long, how many pages did she read on the fourth day?
A: 29
Step-by-step reasoning process: On day two, she read 63 * 2 = 126 pages. On day three, she read 126 + 10 = 136 pages. On day four, she read 354 - 63 - 126 - 136 = 29 pages to finish the book.


Q: During one day, there are 4 boat trips through the lake. The boat can take up to 12 people during one trip. How many people can the boat transport in 2 days?
A: 96
Step-by-step reasoning process: During each boat trip, there can be 12 people onboard, so during 4 boat trips, there can be 4 * 12 = 48 people in total. During two days the boat can transport a total of 48 * 2 = 96 people.
