Benjamin counts 17 + 20 + 23 = 60 billboards total on the way to Los Angeles. Benjamin saw those billboards over 3 hours, so the average number of billboards per hour they saw 60 / 3 = 20 billboards per hour.
The answer: 20
Reverse engineering the question: On their way driving to Los Angeles, Benjamin and James see lots of billboard ads. Curious, Benjamin starts to count how many they see. In the first hour once he starts counting he counts 17 billboards. In the second hour once he starts counting he sees 20 billboards. In the third hour he sees 23 billboards. James asks Benjamin the average number of billboards they've seen per hour. What should Benjamin tell him?


Reasoning and answer: The clown is holding 3 x 12 = 36 balloons. This many children buy a balloon: 3 + 12 = 15 kids. After the children buy the balloons, the clown is holding this many in his hand 36 - 15 = 21 balloons.
The answer: 21
What was the question?
Question: At the circus, the clown has 3 dozen balloons on a string in his hand. 3 boys and 12 girls buy a balloon each. How many balloons is the clown still holding?


If Eugene used all but 16 of the 52 cards, then he used 52 - 16 = 36 cards. If for every card he used 75 toothpicks, then a box of toothpicks would have enough toothpicks for 450 / 75 = 6 cards. Since one box has enough toothpicks for 6 cards, then for 36 cards he would need 36 / 6 = 6 boxes of toothpicks.
The answer: 6
Reverse engineering the question: Eugene built a model house out of toothpicks and a deck of playing cards. For every card, he used 75 toothpicks. The deck of playing cards had 52 cards, and Eugene used all but 16 of the cards to build his house. If a box of toothpicks contains 450 toothpicks, how many boxes of toothpicks did Eugene use to create his model house?


Reasoning and answer: So far Alex and Max are running the race for 200 + 300 + 170 + 440 = 1,110 feet. If the road they're racing each other on is 5000 feet long, 5000 - 1,110 feet = 3,890 feet left for Max to catch up to Alex.
The answer: 3890
What was the question?
Question: Alex and Max are running a race against each other. At the beginning of the race they are even with each other for 200 feet. Then Alex gets ahead of Max by 300 feet. Then Max gets ahead of Alex by 170 feet. Alex gets a burst of speed and gets ahead of Max by 440 feet. If the road they're running on is 5000 feet long, how many feet are there left for Max to catch up to Alex?


Mater:140000(.10) = 14000$. Sally:14000(3) = 42000$.
The answer: 42000
Reverse engineering the question: Lightning McQueen, the race car, cost 140000$. Mater only cost 10 percent of that, and Sally McQueen cost triple what Mater costs. How much does Sally McQueen cost?


Oranges = 12 * 150 = 1800. Nectarines = 16 * 30 = 480. 1800 + 480 = 2280. There are 2280 pieces of fruit in total.
The answer: 2280
Reverse engineering the question:
There are 12 crates that each contain 150 oranges. There are 16 boxes that each hold 30 nectarines. How many pieces of fruit are in the crates and the boxes in total?
