Reasoning and answer: Knowing Kevin's record of eating 70 wings in 8 minutes or 64 / 8 = 8 wings in a minute. Alan must increase his ability to eat 5 wings per minute to 8 - 5 = 3 wings per minute to equal Kevin's world record. To beat Kevin, Alan must eat 3 + 1 = 4 hot wings per minute.
The answer: 4

Danai places 12 skulls + 4 broomsticks + 12 spiderwebs + 1 cauldron = 29 decorations. She also puts up twice as many pumpkins around the house as she put spiderwebs, 12 x 2 = 24 pumpkins. Danai will also add 20 + 10 decorations to the 29 + 24 decorations already up = 83 total decorations Danai will put up.
The answer: 83
Reverse engineering the question: Danai is decorating her house for Halloween. She puts 12 plastic skulls all around the house. She has 4 broomsticks, 1 for each side of the front and back doors to the house. She puts up 12 spiderwebs around various areas of the house. Danai puts twice as many pumpkins around the house as she put spiderwebs. She also places a large cauldron on the dining room table. If Danai has the budget left to buy 20 more decorations and has 10 left to put up, how many decorations will she put up in all?


Reasoning and answer: On Monday, 1200 / 3 = 400 dollars were made. On Tuesday, 1200 / 4 = 300 dollars were made. On Wednesday, 1200 - 400 - 300 = 500 dollars were made.
The answer: 500

Question: A beadshop earns a third of its profit on Monday, a quarter of its profit on Tuesday and the rest of its profit on Wednesday. The shop makes a total profit of $1,200. How much profit, in dollars, was made on Wednesday?


He’s cooking for 8 people and wants to serve 2 scallops per person so he needs 8 * 2 = 16 scallops. 8 jumbo scallops come in 1 pound and he needs 16 scallops so he will need 16 / 8 = 2 pounds of scallops. A pound of scallops weigh $24.00 and he needs 2 pounds so it will cost him 24 * 2 = $48.00 for scallops.
The answer: 48
Reverse engineering the question: 8 jumbo scallops weigh one pound and cost $24.00 a pound. Nate is pairing 2 scallops with a corn bisque as a light summer dinner. He’s cooking for 8 people. How much will the scallops cost?


She loses 5 marbles because 25 x .2 = 5. She has 20 marbles after this because 25 - 5 = 20. Her friend gives her 40 marbles because 20 x 2 = 40. Adding those marbles to the 20 she had before, she ends up with 40 marbles + 20 marbles = 60 marbles.
The answer: 60
Reverse engineering the question:
