Each chicken lays 3 eggs per day and there are 4 chickens 3 * 4 = 12. He will collect all the eggs after 3 days 12 * 3 = 36.
The answer: 36
Reverse engineering the question: Eric has a chicken farm with 4 chickens. His chickens lay 3 eggs each day. If Eric collects all the eggs after 3 days, then how many eggs will Eric have collected?

Let s be the number of still lifes Bethany saw and p be the number of portraits. We know that s + p = 80 and s = 4p. Substituting the second equation into the first equation, we get 4p + p = 80. Combining like terms, we get 5p = 80. Dividing both sides by 5, we get p = 16.
The answer: 16
Reverse engineering the question: At the museum, Bethany saw 4 times more still lifes than portraits. If she saw 80 paintings total, how many portraits did she see?

His first drive was 30 * .5 = 15 miles. The next leg was .5 * 2 = 1 hour. The speed of the trip was 30 * 2 = 60 mph. So he drove 60 * 1 = 60 miles. So in total he drove 60 + 15 = 75 miles.
The answer: 75
Reverse engineering the question: James drives 30 mph for half an hour and then twice as long for twice the speed. How far did he drive in total?

Before throwing the cookies, Alice and Bob baked 74 + 7 = 81 cookies. After throwing the cookies, they baked 5 + 36 = 41 cookies. In total, they baked 81 + 41 = 122 cookies. They threw 122 - 93 = 29 cookies on the floor.
The answer: 29
Reverse engineering the question:
Alice and Bob decided to bake cookies for their first date. Alice baked 74 chocolate chip cookies and Bob baked 7 peanut butter cookies. After accidentally throwing some on the floor, Alice baked 5 more cookies and Bob baked 36 more. If they had 93 edible cookies at the end, how many were accidentally thrown on the floor?
