Each run will hold 7 * 2 = 14 people. The ride will have to run 84 / 14 = 6 times.
The answer: 6
Reverse engineering the question: There are 84 people waiting in line to ride a roller coaster at an amusement park.  The roller coaster has 7 cars, and each car seats 2 people.  How many times will the ride operator have to run the roller coaster to give everyone in line a turn?


Reasoning and answer: Theodore's total earnings from the stone statues are 10 x $20 = $200. His total earnings from wooden statues are 20 x $5 = $100. So his total earnings from the stone and wooden statue are $200 + $100 = $300. The amount he pays for the tax is $300 x 10 / 100 = $30. Therefore his total monthly earnings are $300 - $30 = $270.
The answer: 270

Question: Theodore can craft 10 stone statues and 20 wooden statues every month. A stone statue costs $20 and a wooden statue costs $5. He also pays 10 percent of his total earnings in taxes. How much is his total earning every month?


Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies.
The answer: 2
Reverse engineering the question: Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil’s cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?


Reasoning and answer: 25% of the apples are sour because 100 - 75 = 25. The average price of an apple sold is $.4 because .75(.5) + .25(.1) = .4. He got 100 apples because 40 / .4 = 100.
The answer: 100
What was the question?
Question: Chang's Garden has two kinds of apples. Sweet ones and sour ones. He can sell the sweet ones for $.5 an apple. The sour ones sell for $.1 an apple. 75% of the apples he gets are sweet and the rest are sour. If he earns $40, how many apples did his trees give him?


There are 11 blue x 2 red / blue = 22 red balls. The total number of blue and red balls is 11 blue + 22 red = 33 balls. There are 40 balls - 33 balls = 7 green balls.
The answer: 7
Reverse engineering the question: Ryan has 40 balls. There are twice as many red balls as blue while the rest are green. If there are 11 blue balls, how many green balls are there?


She bought 5 shorts at $7 each so 5 * 7 = $35. She bought 2 pair of shoes at $10 each so 2 * 10 = $20. The shorts and shoes cost her 35 + 20 = $55. We know she spent 75 total and the shorts and shoes cost $55 which left a difference of 75 - 55 = $20. She bought 4 tops for a total of $20 so 20 / 4 = $5.
The answer: 5
Reverse engineering the question:
Ann's favorite store was having a summer clearance. For $75 she bought 5 pairs of shorts for $7 each and 2 pairs of shoes for $10 each. She also bought 4 tops, all at the same price. How much did each top cost?
