Q: Carla is taking attendance for her sixth-grade class. She knows that 2 students are in the restroom, and one less than three times that number of students are absent. If there are four rows with six desks each that are all 2/3 full, how many students does Carla teach, including the ones in and out of the classroom?
A: First find the number of absent students: 2 students * 3 - 1 = 5 students. Now find the number of students in each row of desks: 6 desks / row * 2 students / 3 desks = 4 students / row. Now find the number of students in all the rows: 4 rows * 4 students / row = 16 students. Now add the students that are absent or in the bathroom: 16 students + 2 students + 5 students = 23 students. The answer is 23.
Question: John attends a protest for 4 days. He then attends a second protest for 25% longer than the first. How many days did he spend protesting?
Answer: The second protest was 4 * .25 = 1 day longer than the first. So the second protest was 4 + 1 = 5 days. Thus he spent 4 + 5 = 9 days protesting. The answer is 9.
[Question]Mrs. Lim milks her cows twice a day. Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50?
[Answer]Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616. The answer is 616.
Q: Jack went to a supermarket with $100 and bought 4 bottles of water. Then his mother called him and asked him to buy twice as many bottles as he already bought. Each bottle cost $2. Finally, he also bought half a pound of cheese and 1 pound of cheese costs $10. How much money does Jack have remaining?
A: Jack's mother asked him to buy 2 * 4 = 8 bottles of water. Thus Jack bought 4 + 8 = 12 bottles of water in total. Altogether, the bottles of water cost 12 * $2 = $24. The cheese cost 1 / 2 * $10 = $5. So Jack spent $24 + $5 = $29 on water and cheese. Since he started with $100, he now has $100 - $29 = $71 left. The answer is 71.
Question: Connie redeemed all her arcade tickets today. She spent half of them on a stuffed koala bear. She spent 10 tickets on a pair of earbuds. She spent another 15 tickets on glow bracelets. How many tickets did Connie redeem today?
Answer: Connie spent 10 tickets on earbuds + 15 tickets on glow bracelets = 25 tickets. Since Connie spends half of her tickets on a stuffed koala bear, that means the 25 tickets she spent on earbuds and glow bracelets is the other half, so she spent 25 tickets on the stuffed koala bear. In all, Connie spent 25 tickets on earbuds and glow bracelets + 25 tickets on a stuffed koala bear = 50 tickets. The answer is 50.
Q: Nancy, the librarian, is shelving books from the cart. She shelved 12 history books, 8 romance books, and 4 poetry books from the top section of the cart. Half the books on the bottom section of the cart were mystery books, which she quickly put back into place. Then, she shelved the remaining books from the bottom of the cart, including 5 Western novels and 6 biographies. How many books did she have on the book cart when she started?
A:
Half of the books on the bottom section of the cart are mystery books, which means they are the same as the number of Western novels and biographies put together. So there are 5 + 6 = 11 mystery novels. Add them all together, and there are 12 history + 8 romance + 4 poetry + 11 mystery + 5 Western + 6 biographies = 46 books total. The answer is 46.
