Megan has 12 + 12 = 24 eggs. After making her omelet and cake, she was left with 24 - 2 - 4 = 18 eggs. After giving half to her aunt, she was left with 18 / 2 = 9. Megan would have 9 / 3 = 3 eggs per meal for the next three meals.
The answer: 3
Reverse engineering the question: Megan went to the store and bought a dozen eggs. When she got home, her neighbor gave her another dozen eggs from her chickens. Megan used 2 eggs to make an omelet for dinner and 4 eggs to bake a cake. When Megan's aunt came over for a visit, Megan gave her half of her remaining eggs. How many eggs per meal would Megan have if she plans to divide what she has left equally for her next 3 meals?


Reasoning and answer: 81 / 3 = 27 students are wearing checkered shirts. 27 x 2 = 54 students are wearing striped shirts. 27 + 19 = 46 students are wearing shorts. 54 - 46 = 8 more students are wearing striped shirts than shorts.
The answer: 8
What was the question?

Her friends will eat 16 slices of cake because 8 x 2 = 16. There will be 19 slices eaten in total because 16 + 3 = 19. She is making 24 slices of cake because 4 x 6 = 24. There will be 5 pieces left over because 24 - 19 = 5.
The answer: 5

Reasoning and answer: Since there are 20 fewer mittens pairs than the plugs, there are 150 + 20 = 170 pairs of plugs. When Gunner decides to add 30 more plugs pairs into the box of plugs, the number of plug pairs increases to 170 + 30 = 200. Since a pair has two, the 200 pairs of plugs total 200 * 2 = 400 plugs.
The answer: 400
