Question: Jack bought 3 books a month at $20 each. He sells them back at the end of the year for $500. How much money did he lose?
Answer: He bought 3 * 20 = $60 of books a month. That means he bought 60 * 12 = $720 of books a year. So he lost 720 - 500 = $220. The answer is 220.
[Question]There is a 5,200 sq. ft. house and a 7,300 sq. ft. house next to each other. The smaller house is being expanded. If the new total square footage of both houses is 16,000 sq. ft., how much is the smaller house being expanded by, in sq. ft.?
[Answer]Originally, the houses are 7300 + 5200 = 12500 sq. ft. in total. The smaller house will be expanded by 16000 - 12500 = 3500 sq. ft. The answer is 3500.
Q: Tammy just got her hair cut. For every 14 haircuts, she gets a free additional haircut. She has gotten 5 free haircuts already. She is 5 haircuts away from another free one. How many haircuts has she gotten there?
A: She has gotten 70 haircuts to get 5 free ones because 14 x 5 = 70. She has gotten 9 haircuts towards her 6th free one because 14 - 5 = 9. She has gotten 79 haircuts because 70 + 9 = 79. The answer is 79.
Question: Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?
Answer: First find the total distance Carson walks along the warehouse's long sides: 600 feet / side * 2 sides = 1200 feet. Then find the total distance Carson walks along the warehouse's short sides: 400 feet / side * 2 sides = 800 feet. Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 2000 feet. Then find the number of circles Carson actually walks: 10 circles - 2 circles = 8 circles. Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet / circle * 8 circles = 16000 feet. The answer is 16000.
[Question]In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards?
[Answer]The difference in cubic yards between the two cities is 9000 - 6400 = 2600 cubic yards. Since the number of people living in a city per cubic yard is 80, there are 80 * 2600 = 208000 more people living in a city with 9000 cubic yards than a city with 6400 cubic yards. The answer is 208000.
