Q: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
A: First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds. The answer is 270.
Question: Sally teaches elementary school and is given $320 to spend on books for her students. A reading book costs $12 and there are 30 students in her class. Unfortunately, if the money she is given by the school to pay for books is not sufficient, she will need to pay the rest out of pocket. How much money does Sally need to pay out of pocket, to buy every student a reading book?
Answer: To purchase a book for each student, Sally needs: 30 x $12 = $360. She thus needs to pay $360 - $320 = $40 out of pocket. The answer is 40.
[Question]Davonte is trying to figure out how much space his art collection takes up. He measures his paintings and finds he has three square 6-foot by 6-foot paintings, four small 2-foot by 3-foot paintings, and one large 10-foot by 15-foot painting. How many square feet does his collection take up?
[Answer]His square paintings take up 36 square feet each because 6 x 6 = 36. His small paintings take 6 square feet each because 2 x 3 = 6. His large painting takes up 150 square feet because 10 x 15 = 150. Combined, his square paintings take up 108 square feet because 3 x 36 = 108. Combined, his small paintings take up 24 square feet because 4 x 6 = 24. In total, his paintings take up 282 square feet because 150 + 108 + 24 = 282. The answer is 282.
Q: John buys a lightsaber toy. It is twice as expensive as all his other Star Wars toys combined. If his other Star Wars toys cost $1000, how much money has he spent in all after buying the lightsaber?

Question: The last time Bob cut his hair he cut it to 6 inches. His hair is now 36 inches long. If hair grows at a rate of .5 inches per month how many years did it take him to grow out his hair?
Answer: His hair grew 36 inches - 6 inches = 30 inches. Hair grows at a rate of 12 months / year * 0.5 inches / month = 6 inches / year. It took him 30 inches / 6 inches / year = 5 years to grow his hair out. The answer is 5.
Q: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
A:
Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans. The answer is 5.
