Reasoning and answer: The shirts weigh 20 / 4 = 5 pounds. The pants weigh 20 / 2 = 10 pounds. So he needs to do 10 + 5 = 15 pounds of laundry. So that would take 15 / 5 = 3 loads of laundry.
The answer: 3

Marlene wants to buy 12 / 2 = 6 shirts. The discount price of the shirt is $50 x 20 / 100 = $10. So, the shirt will only costs $50 - $10 = $40 each. Thus, Marlene will pay $40 x 6 = $240 for the 6 shirts.

Reasoning and answer: The shark went from 20 miles per hour to a speed of 2 * 20 = 40 miles per hour. The shark increased its speed by 40 - 20 = 20 miles per hour. Half of the shark's increase in speed is 20 / 2 = 10 miles per hour. Thus the pilot fish had increased its speed to 20 + 10 = 30 miles per hour.
The answer: 30

Question: Keanu was surfing towards the shore at a speed of 20 miles per hour. A shark was swimming alongside him, riding the same wave, when it doubled its speed and moved away from Keanu. There was a pilot fish swimming alongside Keanu and the shark, and when the shark increased its speed, the pilot fish also increased its speed and moved away from Keanu, but only increasing its speed by half as much as the shark had increased its speed by. What speed, in miles per hour, was the pilot fish swimming when it moved away from Keanu?
Joey studies 2 hours a night 5 nights a week so that's 2 * 5 = 10 hours. He studies 3 hours a day on the weekends so that's 3 * 2 = 6 hours. In one week, Joey studies 10 + 6 = 16 hours. He has 6 weeks till his exams and he studies for 16 hours a week so that's 6 * 16 = 96 hours of studying.
The answer: 96
Reverse engineering the question: Joey studies for his SAT exams 2 hours per night 5 nights a week. On the weekends, he studies 3 hours a day. If his SAT exam is 6 weeks away, how much time will Joey spend studying?
Reasoning and answer: In a day, John uses 75x 8 = 600 watts. So in a month, he uses 600 x 30 = 18 000 watts. Since there are 1000 watts in 1 kilowatt, then John uses 18000 / 1000 = 18.
The answer: 18

Reasoning and answer: The length of the box is 3 x the height of 12 inches = 36 inches. The width of the box is 36 inches / 4 = 9 inches. The volume of the box is the height of 12 inches x the length of 36 inches x the width of 9 inches = 3,888 cubic inches.
The answer: 3888
