[Question]Andy gets a cavity for every 4 candy canes he eats. He gets 2 candy canes from his parents and 3 candy canes each from 4 teachers. Then he uses his allowance to buy 1/7 as many candy canes as he was given. How many cavities does he get from eating all his candy canes?
[Answer]First find how many candy canes Andy gets from his teachers: 3 canes / teacher * 4 teachers = 12 canes. Then add the number of candy canes he gets from his parents: 12 canes + 2 canes = 14 canes. Then divide that number by 7 to find the number of canes he buys: 14 canes / 7 = 2 canes. Then add the number of candy canes he gets from each source to find the total number: 2 canes + 14 canes = 16 canes. Then divide the total number of candy canes by the number of candy canes it takes to get one cavity to find the number of cavities Andy gets: 16 canes / 4 canes / cavity = 4 cavities. The answer is 16.
Q: Sarah is checking out books from the library to read on vacation. She can read 40 words per minute. The books she is checking out have 100 words per page and are 80 pages long. She will be reading for 20 hours. How many books should she check out?
A: Each book has 8,000 words because 100 x 80 = 8,000. She can finish each book in 200 minutes because 8,000 / 40 = 200. She will be reading for 1,200 minutes because 20 x 60 = 1,200. She needs to check out 6 books because 1,200 / 200 = 6. The answer is 6.
Question: Ajax is 80 kilograms. He is planning to lose some weight. Exercising for an hour will help him lose 1.5 pounds. If 1 kilogram is equal to 2.2 pounds How many pounds will he weigh if he exercises for 2 hours every day for two weeks?
