Q: Every day, Sara bakes 10 cakes and puts them in his refrigerator. He does this for 5 days. Carol then comes over and eats 12 of his cakes. If it takes 2 cans of frosting to frost a single cake, how many cans of frosting does Bob need to frost the remaining cakes?
A: After 5 days, Sara has baked 5 days * 10 cakes / day = 50 cakes. After Carol's feast, there are 50 cakes - 12 cakes = 38 cakes remaining. Sara needs 2 cans / cake * 38 cakes = 76 cans of frosting. The answer is 76.
Question: A certain tree was 100 meters tall at the end of 2017. It will grow 10% more than its previous height each year. How long has the tree grown from 2017 until the end of 2019?
Answer: At the end of 2018, the tree will grow 100 x 10 / 100 = 10 meters more. Thus, its height at the end of 2018 is 100 + 10 = 110 meters. At the end of 2019, the tree will grow 110 x 10 / 100 = 11 meters more. So, its height at the end of 2019 is 110 + 11 = 121 meters. Therefore, the tree has grown 121 - 100 = 21 meters. The answer is 21.
[Question]There are 36 seagulls on the roof of the Taco Bell. Kids scare 1/4 of them away by throwing stones, and 1/3 of the remaining birds decide to fly to McDonald's parking lot. How many seagulls are left?
[Answer]First find how many birds get scared away by kids: 36 seagulls / 4 = 9 seagulls. Then subtract that number from the starting total: 36 seagulls - 9 seagulls = 27 seagulls. Then divide that number by 3: 27 seagulls / 3 = 9 seagulls. Then subtract that number from the 27 seagulls to find the final number of seagulls: 27 seagulls - 9 seagulls = 18 seagulls. The answer is 18.
Q: 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?
A: 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.
