[Question]The school is having a book-a-thon. The winning class gets a pizza party. The fifth grade has 20 students and one week to read as much as possible. The 6th grade already finished and read a total of 299 hours. How many hours does each student in 5th grade need to average per day to beat them by 1?
[Answer]The class needs to read 300 hours in a week because 299 + 1 = 300. The class needs to read 60 hours a day because 300 / 5 = 60. Each student needs to read 3 hours a day because 60 / 20 = 3. The answer is 3.
Q: Lawrence worked 8 hours each day on Monday, Tuesday and Friday. He worked 5.5 hours on both Wednesday and Thursday. How many hours would Lawrence work each day if he worked the same number of hours each day?
A: 8 hours * 3 = 24 hours. 5.5 * 2 = 11 hours. 24 + 11 = 35 hours. 35 / 7 = 5 hours. Lawrence would work 5 hours each of the 7 days in a week. The answer is 5.
Question: Sue and her sister buy a $2,100 car. They agree to split the cost based on the percentage of days use. Sue's sister will drive the car 4 days a week and Sue will get the rest of the days. How much does Sue have to pay?

[Question]The vending machine fails to drop a snack when it’s purchased one in six times. One in ten times, it will accidentally drop two snacks. The rest of the time, it drops the purchased snack. If thirty people have used the vending machine once each to purchase a snack, how many snacks has the vending machine dropped?
[Answer]The vending machine has been used 30 times, so it has failed to drop a snack 30 / 6 = 5 times. The vending machine has dropped 2 snacks 30 / 10 = 3 times. It has operated normally and dropped 1 snack 30 - 5 - 3 = 22 times. Thus, the vending machine has dropped 22 + 3 * 2 = 22 + 6 = 28 snacks in thirty uses. The answer is 28.
Q: Suzanna's history textbook has 160 pages and her geography textbook has 70 more pages. Her math textbook has half of the sum of the first two books' pages, and her science textbook has twice the number of pages of her history textbook. If Suzanna stacks all her textbooks on her desk, how many pages would there be in total?
A: Her geography textbook has 160 + 70 = 230 pages. The sum of pages of her history and geography textbook is 160 + 230 = 390 pages. Her math textbook has 390 / 2 = 195 pages. Her science textbook has 160 x 2 = 320 pages. In total, there would be 160 + 230 + 195 + 320 = 905 pages. The answer is 905.
Question: Wilson decides to go sledding on some nearby hills. On the 2 tall hills, he sleds down them 4 times each and on the 3 small hills, he sled down them half as often as he sleds down the tall hills. How many times did he sled down the hills?
Answer:
On the tall hills, he sleds down 2 tall hills * 4 times per tall hill = 8 times. He sleds down the small hills half as often so he sleds down each hill 4 times per tall hill / 2 = 2 times per small hill. On the small hills, he sleds down 3 small hills * 2 times per small hill = 6 times. So in total, Wilson sled down the hills 8 times on tall hills + 6 times on small hills = 14 times. The answer is 14.
