Question: Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo?
Answer: In the bottom half of the igloo, there are 10 rows / 2 = 5 rows of bricks of snow. So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = 60 bricks of snow. In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = 40 bricks of snow. There is therefore a total of 60 + 40 = 100 bricks of snow in the igloo. The answer is 100.
[Question]For breakfast, Anna bought a bagel for $0.95 and a glass of orange juice for $0.85. At lunch, Anna spent $4.65 on a sandwich and $1.15 on a carton of milk. How much more money did Anna spend on lunch than on breakfast?
[Answer]The total cost of breakfast is $0.95 + $0.85 = $1.80. The total cost of lunch is $4.65 + $1.15 = $5.80. Anna spent $5.80 − $1.80 = $4 more on lunch than breakfast. The answer is 4.
Q: When Patrick, Manu, and Amy participate in a race they realize that Patrick finishes the race in 60 seconds. Manu took 12 more seconds to finish the race. If Amy is twice as fast as Manu, how long did it take her to finish the race?
A: The time it took Manu to complete the race is 60 + 12 = 72 seconds. If Amy is twice as fast as Manu, then she takes half the time Manu did to finish the race, so Amy took 1 / 2 * 72 = 36 seconds. The answer is 36.
Question: Saturday at the ice cream shop, there were twice as many people who ordered vanilla ice cream as ordered chocolate ice cream. If 220 people ordered ice cream on Saturday, and 20% of those ordered vanilla ice cream, how many people ordered chocolate ice cream?
Answer: If 20% of 220 customers ordered vanilla, then there were 0.2 * 220 = 44 customers who ordered vanilla. If there were twice as many people who ordered vanilla as chocolate, then 44 / 2 = 22 customers ordered chocolate. The answer is 22.
[Question]Yvette wants to frame a new picture. When she goes to her local frame shop, she finds out that the frame she wanted is 20% more expensive than her budget of $60. If she paid for a smaller frame at 3/4 the new price of the frame she initially intended to buy, how much money did she remain with?
[Answer]The frame she initially intended to buy was 20 / 100 * $60 = $12 more expensive than she had thought. This means the frame was being sold at $60 + $12 = $72. If she paid for a smaller frame at 3 / 4 the price of the frame she initially intended to buy, she paid 3 / 4 * $72 = $54. Yvette remained with $60 - $54 = $6. The answer is 6.
[Question]A lot of people have been sick at Gary's workplace, so he's been working a lot of extra shifts to fill in for people. As a result, he's earned some overtime (where every hour after 40 he earns 1.5 times his normal wage.) His paycheck (before taxes are taken out) came out to $696. If Gary normally earns $12 per hour, how many hours did he work that week?
[Answer]
Gary earned overtime, so he worked at least 40 hours. for which he was paid 40 hours * $12 / hour = $480 at his normal wage. This means that $696 - $480 = $216 was earned at his overtime wage. His overtime wage is 1.5 his normal wage, or $12 * 1.5 = $18 per hour. So Gary worked $216 / $18 per hour = 12 hours' worth of overtime. So in total, Gary worked 40 hours + 12 hours = 52 hours that week. The answer is 52.
