Reasoning and answer: If Allie's bowl contained two more grapes than Rob's bowl, there were 25 + 2 = 27 grapes in Allie's bowl. If Allyn's bowl contained four more grapes than Allie's bowl, there were 27 + 4 = 31 grapes in Allyn's bowl. The total combined number of grapes in all three bowls is 25 + 27 + 31 = 83 grapes.
The answer: 83

Each box contains 4 * 2 = 8 crayons. In an hour, they make 8 * 5 = 40 crayons. In 4 hours they make 4 * 40 = 160 crayons.
The answer: 160
Reverse engineering the question: A crayon factory makes 4 colors of crayons. They put 2 of each color crayon in each box. The factory produces enough crayons to fill 5 boxes per hour. How many crayons does the factory produce in 4 hours?
Reasoning and answer: The volume of the slab is 100 * 100 * .5 = 5000 cubic feet. So it weighs 5000 * 150 = 750000 pounds. That means the cost is 750000 * $0.02 = $15,000 per house. So the total cost for all 3 houses is $15000 * 3 = $45,000.
The answer: 45000

Lillian found 9 of the mushrooms were safe, so there were 32 - 9 = 23 that she found poisonous or uncertain. She knew twice the amount she ate were poisonous, so she found 9 * 2 = 18 poisonous mushrooms. Thus, she was uncertain about 23 - 18 = 5 mushrooms.
The answer: 5
Reverse engineering the question: Lillian went out to forage for mushrooms with her handy guidebook. She found 32 mushrooms and used her guidebook to identify which ones were poisonous and which were safe to eat. In the end, she had 9 mushrooms she could safely eat for dinner. Of the rest, she identified twice the amount she ate as poisonous, and a remaining bunch she was uncertain about. How many mushrooms was she uncertain were safe or poisonous?
Reasoning and answer: Let D be the cost of the dessert in dollars. The entree costs D + 5 dollars. D + (D + 5) = 23. 2D + 5 = 23. 2D = 18. D = 9. The entree costs $14.
The answer: 14

Question: Hannah is at a restaurant. She spends $23 in total on an entree and a dessert. If the entree costs $5 more than the dessert, how much does the entree cost, in dollars?
Reasoning and answer: Sarah and the final neighbor took the wrong amount, which means that 15 neighbors 1 Sarah 1 final neighbor = 13 neighbors took 10 cookies each. This is a total of 13 neighbors * 10 cookies = 130 cookies taken by the first 13 neighbors. There were only 8 cookies left, so that means the first 13 neighbors and Sarah took a total of 150 8 = 142 cookies. So Sarah must have taken 142 130 = 12 cookies.
The answer: 12

Question:
Edna made cookies for all of her neighbors and left the cookies outside for them to take. She made 150 cookies so her 15 neighbors could get 10 cookies each. However, the neighbor who arrived last told Edna there were only 8 cookies left. Edna thinks it was Sarah who took too many cookies. If all the other neighbors took the correct amount of cookies, how many cookies did Sarah take?
