The carpenter made 10 - 3 = 7 tables last month. So, the carpenter made 10 + 7 = 17 tables in all.
The answer: 17
Reverse engineering the question: A carpenter made ten tables for this month. Last month, he made three fewer tables than this month. How many tables did the carpenter make in total?


Reasoning and answer: His old apartment cost 750 * $2 = $1500 a month. His new apartment cost $2800 / 2 = $1400 a month. So he saves $1500 - $1400 = $100 a month. That means he saves $100 * 12 = $1200 a year.
The answer: 1200

Question: John decides to get a new apartment with a roommate. His former rent was $2 per square foot for a 750 square foot apartment. His new apartment cost $2800 per month, which he splits evenly with the roommate. How much money does he save a year?


Miles will read for 4 hours because 24 x (1 / 6) = 4. He will read each type for 1 and 1 / 3 hours because 4 / 3 = 1 and 1 / 3. He will read 28 pages of novels because 21 x (1 and 1 / 3) = 28. He will read 40 pages of graphic novels because 30 x (1 and 1 / 3) = 40. He will read 60 pages of comic books because 45 x (1 and 1 / 3) = 60. He will read 128 pages in total because 28 + 40 + 60 = 128.
The answer: 128
Reverse engineering the question: Miles is going to spend 1/6 of a day reading. He will read comic books, graphic novels, and novels. He reads 21 pages an hour when he reads novels, 30 pages an hour when he reads graphic novels, and 45 pages an hour when he reads comic books. If he reads each for 1/3 of his time, how many pages does he read?


Reasoning and answer: The 12 linemen go first and will drink a total of 12 * 8 = 96 ounces of water from the cooler. This will leave 126 - 96 = 30 ounces for the skill position players. Then, the 30 ounces of water that remains is enough for 30 / 6 = 5 of the skill position players. Therefore, 10 - 5 = 5 skill position players must wait for the cooler to be refilled before they can get a drink.
The answer: 5
What was the question?
Question: A football team shares a single water cooler during practice. During practice, linemen get the first water break and will drink 8 ounces each. Skill position players get the second water break and drink 6 ounces each. The team has 12 linemen and 10 skill position players. If the cooler holds 126 ounces of water, how many skill position players must wait for the cooler to be refilled before they can get a drink?


Joe’s dad roasts 21 / 3 = 7 of his marshmallows. Joe has 21 * 4 = 84 marshmallows. Joe roasts 84 / 2 = 42 of his marshmallows. Joe and his dad roasted 7 + 42 = 49 marshmallows in total.
The answer: 49
Reverse engineering the question: Joe goes camping with his dad on a Friday. Joe's dad has 21 marshmallows, and Joe has four times as much marshmallows as his dad. If Joe’s dad roasts a third of his marshmallows, and Joe roasts half of his marshmallows, how many marshmallows did they roast in total?


The 6 gifts will use 6 x 2 = 12 yards of ribbon. So, 18 - 12 = 6 yards of ribbon will be left.
The answer: 6
Reverse engineering the question:
Josh has 18 yards of ribbon that is to be used equally to 6 gifts. If each gift will use 2 yards of ribbon, how many yards of ribbon will be left?
