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? Give the rationale and then the answer.
Let's think step by step. 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 is: 20.

Luisa drives 10 miles to the grocery store, 6 miles to the mall, 5 miles to the pet store, then 9 miles back home. One gallon of gas can be used to drive 15 miles. If one gallon of gas costs $3.50, what is the total cost of the gas for Luisa’s entire trip? Give the rationale and then the answer.
Let's think step by step. Luisa drives a total of 10 + 6 + 5 + 9 = 30 miles. Luisa uses 30 / 15 = 2 gallons of gas for her trip. The total cost of the gas for Luisa’s trip is 2 * $3.50 = $7.. The answer is: 7.

There were 60 women at the party, and three-fourths of these women were married and brought their husbands with them to the party. If 3/4 of the men at the party were single, how many people attended the party? Give the rationale and then the answer.
Let's think step by step. 60 x 3 / 4 = 45 females are married which means there are also 45 married males. If 1 / 4 of the men are married, which represents 45 men, then 4 * 45 = 180 is the total number of men who attended the party. Thus, there are a total of 60 women and 180 men, or a total of 60 + 180 = 240 people at the party.. The answer is: 240.
