Matthew picked 16 + 20 = 36 strawberries. Natalie picked 36 / 2 = 18 strawberries. All together, they have 16 + 36 + 18 = 70 strawberries. They can make 70 / 7 = 10 jars of strawberries. They earn 10 x $4 = $40 from the strawberries they picked.
The answer: 40
Reverse engineering the question: Betty picked 16 strawberries. Matthew picked 20 more strawberries than Betty and twice as many as Natalie. They used their strawberries to make jam. One jar of jam used 7 strawberries and they sold each jar at $4. How much money were they able to make from the strawberries they picked?


Reasoning and answer: First find the number of cars in Section G by multiplying the number of rows by the number of cars per row: 15 rows * 10 cars / row = 150 cars. Then do the same thing for Section H: 20 rows * 9 cars / row = 180 cars. Then add the two quantities of cars to find the total number of cars Nate walked past: 150 cars + 180 cars = 330 cars. Finally, divide the number of cars Nate passed by the numbers he passes each minute to find how long he spent searching: 330 cars / 11 cars / minute = 30 minutes.
The answer: 30
What was the question?
Question: Nate got lost looking for his car in the airport parking lot. He had to walk through every row in Section G and Section H to find it. Section G has 15 rows that each hold 10 cars. Section H has 20 rows that each hold 9 cars. If Nate can walk past 11 cars per minute, how many minutes did he spend searching the parking lot?


Under 30: 40(.10) = 4. 30 - 50 years old:40(.60) = 24. Over 50:40 - 4 - 24 = 12 Judges.
The answer: 12
Reverse engineering the question: There are 40 Judges in the state of Rhode Island. 10 percent of Judges are under 30 years old. 60 percent of Judges are 30-50 years old. The rest of the Judges are over 50 years old. How many Judges are over 50 years old?


Reasoning and answer: Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12 / 2 = 6 commencement addresses. The two of them gave 6 + 12 = 18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12 + 10 = 22 commencement addresses. The three of them gave 22 + 18 = 40 commencement addresses.
The answer: 40
What was the question?
Question: In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?


He has 3 apples and 4 bananas, so he has 3 + 4 = 7 pieces of fruit. He needs to buy 12 fruit - 7 fruit = 5 oranges.
The answer: 5
Reverse engineering the question: Mark is looking to buy a total of 12 pieces of fruit at the store. He has already chosen 3 apples. He has also selected a bunch of bananas containing 4 bananas. How many oranges does he need to pick out to have 12 total pieces of fruit?


Janice walks up 3 flights of stairs 5 times per day, for a total of 3 * 5 = 15 flights of stairs. Janice walks down 3 flights of stairs 3 times per day, for a total of 3 * 3 = 9 flights of stairs. In total, she walks 15 + 9 = 24 flights of stairs in a single day.
The answer: 24
Reverse engineering the question:
Janice's office is on the third floor, and she has to walk up 3 flights of stairs to get to her office. In a single day, she goes up the three flights of stairs 5 times, down the the three flights of stairs 3 times, and uses the elevator the remainder of the time. How many flights of stairs does Janice walk (up and down) in a single day?
