The cost was 3 * 5 = $15. So he got 20 - 15 = $5 in change.
The answer: 5
Reverse engineering the question: Jack orders 3 sandwiches that cost $5 each. He pays with a $20 bill. How much does he get in change?


Reasoning and answer: He listens to 2 * 60 = 120 minutes of music a day. So he hears 200 * 120 = 24000 beats per day. That means he hears 24,000 * 7 = 168,000 beats per week.
The answer: 168000

Question: James listens to super-fast music. It is 200 beats per minute. He listens to 2 hours of music a day. How many beats does he hear per week?


The price increase raised the price by 1.6 * .25 = $.4. So each pound of apples cost 1.6 + .4 = $2. 2 * 4 = 8 pounds of apples are bought. So the apples cost 8 * 2 = $16.
The answer: 16
Reverse engineering the question: Apples used to cost $1.6 per pound. The price got raised 25%. How much does it cost to buy 2 pounds of apples for each person in a 4 member family?


Reasoning and answer: If Mallory gammy's house is 2000 miles away and she has to refill the fuel tank every 500 miles, she filled the tank 2000 / 500 = 4 times. If each refill costs $45, the total amount of money she used on refilling the tank is $45 * 4 = $180. The food cost was 3 / 5 times as much as the fuel costs, which is 3 / 5 * $180 = $108. On the whole journey, Mallory expenses on fuel and food costs are $108 + $180 = $288.
The answer: 288
What was the question?
Question: The cost of filling a car fuel tank is $45, and this can take you 500 miles before refilling. Mallory was going to her grammy's house, 2000 miles away. If she used 3/5 times as much money on food as she spent on filling the car fuel tank for the whole journey, calculate the total amount of money she used.


The teams have 33 total wins because 12 + 13 + 8 = 33. The teams have 66 points from wins because 33 x 2 = 66. The teams have 15 total ties because 4 + 1 + 10 = 15. The teams have 15 points from ties because 15 x 1 = 15. The teams have 81 total points because 66 + 15 = 81. The average number of points per team is 27 because 81 / 3 = 27.
The answer: 27
Reverse engineering the question: Elsa's hockey team just made the playoffs along with two other teams. They make the playoffs by having the top three highest points for their records. Teams get 2 points for a win, 1 point for a tie, and zero points for a loss. The first-place team has 12 wins and 4 ties. The second-place team has 13 wins and 1 tie. Elsa's team has 8 wins and 10 ties. What is the average number of points for the playoff teams?
