Q: Colton had 72 dolphin stickers. He gave 4 stickers each to 3 friends. He also gave his friend Mandy 2 more than he gave his three friends total.  And he gave Justin 10 less than Mandy. How many stickers does Colton have left?
A: Colton gave away 4 stickers * 3 friends = 12 stickers. Colton gave Mandy 2 + 12 stickers = 14 stickers. Colton gave Justin 14 stickers - 10 = 4 stickers. In total, Colton gave away 12 + 14 + 4 stickers = 30 stickers. Colton's number of total stickers at the end is 72 - 30 = 42 stickers. The answer is 42.
Question: James has an old printer that crumples every seventh page and blurs the ink on every third page. If he prints 42 pages, how many are neither crumpled or blurred?
Answer: First find the total number of pages that are crumpled: 42 pages / 7 = 6 pages. Then find the total number of pages that are blurred: 42 pages / 3 = 14 pages. Then find the number of pages that are both blurred and crumpled by finding how many numbers are less or equal to 42 and divisible by both 3 and 7: there are two, 21 and 42. Then subtract the number of crumpled and blurred pages from the total number of pages, and add the number of pages that were double - counted because they were both blurred and crumpled: 42 pages - 6 pages - 14 pages + 2 pages = 24 pages. The answer is 24.
[Question]A town is trying to clear litter from its streets. The council pays for adding 14 trash cans to the streets and also pays for adding twice as many trash cans to the back of stores. How many trash cans has the town paid for?
[Answer]At the back of stores, the town has paid for 14 trash cans on the streets * 2 = 28 trash cans. The town has therefore added 14 trash cans on the streets + 28 trash cans at the back of stores = 42 trash cans. The answer is 42.
Q: Pete has a bag with 10 marbles. 40% are blue and the rest are red. His friend will trade him two blue marbles for every red one. If Pete keeps 1 red marble, how many total marbles does he have after trading with his friend?
A: He starts with 4 blue marbles because 10 x .4 = 4. 60% of the marbles are red because 100 - 40 = 60. He has 6 red marbles because 10 x .6 = 6. He trades 5 red marbles because 6 - 1 = 5. He gets 10 blue marbles because 5 x 2 = 10. He has 15 marbles now because 4 + 1 + 10 = 15. The answer is 15.
Question: Kyle is 5 years older than Julian. Julian is 20 years younger than Frederick. Frederick is 2 times older than Tyson. If Tyson is 20, how old is Kyle?
