Since he fires his weapon on average every 15 seconds, then in one minute he fires the flamethrower 60 / 15 = 4 times. And since each time he fires his weapon, he shoots flame for 5 seconds, then Jason shoots flames at the dragon hoard a total of 4 * 5 = 20 seconds of every minute.
The answer: 20
Reverse engineering the question: When Jason plays the video game, Duty for Ashes, his mission to slay the dragon hoard requires that he fire his weapon on average every 15 seconds.  And each time he fires his weapon, his power-fire setting allows him to shoot a flame for 5 seconds. On average, how many seconds per minute does Jason shoot flames at the dragon hoard?


Reasoning and answer: Combining the three classes, there are 17 + 14 + 15 = 46 male students. Similarly, there are 13 + 18 + 17 = 48 female students. Thus, there are 48 - 46 = 2 students who cannot partner with a student of the opposite gender.
The answer: 2
What was the question?
Question: Three different 6th grade classes are combining for a square dancing unit. If possible, the teachers would like each male student to partner with a female student for the unit. The first class has 17 males and 13 females, while the second class has 14 males and 18 females, and the third class has 15 males and 17 females. When the classes are combined, how many students will be unable to partner with a student of the opposite gender?


Allison bought 8 + 15 = 23 glue sticks. Allison bought 30 / 6 = 5 packs of construction paper. Allison bought 23 + 5 = 28 craft supply items.
The answer: 28
Reverse engineering the question: Allison went to the craft store with her friend Marie to buy some glue sticks and construction paper. Allison bought 8 more glue sticks than Marie, but Marie bought six times as many packs of construction paper as Allison. If Marie bought 15 glue sticks and 30 packs of construction paper how many craft supply items did Allison buy all together?


Reasoning and answer: In a week, Mr. Alvarez uses $36 / $3 = 12 gallons a week. So in two weeks, he uses 12 x 2 = 24 gallons.
The answer: 24
What was the question?
Question: Mr. Alvarez spends $36 on diesel fuel each week. If the cost of diesel fuel is $3 per gallon, how many gallons of diesel fuel does Mr. Alvarez use in two weeks?


She served 20 people and they all tipped her $1.25 so she made 20 * 1.25 = $25.00 in tips. She makes $12.00 an hour and she made $25.00 in tips so she made 12 + 25 = $37.00 in one hour.
The answer: 37
Reverse engineering the question: Rachel makes $12.00 as a waitress in a coffee shop. In one hour, she serves 20 different people and they all leave her a $1.25 tip. How much money did she make in that hour?


The extra cost for coloring is 160 * .5 = $80. So the total cost was 160 + 80 = $240.
The answer: 240
Reverse engineering the question:
John commissions an artist to make him a 9 by 13 drawing. A black and white drawing that size would cost $160. He wants a color drawing so that is 50% more expensive. How much did he pay?
