[Question]Last night, Olive charged her phone for 10 hours. Assuming each hour of charge lasts the phone 2 hours of use, calculate the total time Olive would be able to use her phone before it goes off if she charges it for 3/5 of the time she charged the phone last night.
[Answer]If Olive charges her phone for 3 / 5 of the time she charged the phone last night, the phone would be charged for 3 / 5 * 10 = 6 hours. Assuming each hour of charge lasts the phone 2 hours of use, the phone will last for 6 * 2 = 12 hours before it goes off when Olive uses it on a six hours charge. The answer is 12.

[Question]Page collects fancy shoes and has 80 pairs in her closet. She decides to donate 30% of her collection that she no longer wears. After dropping off her donation, she treats herself and buys 6 more pairs to add to her collection. How many shoes does she have now?
[Answer]She donates 30% of her 80 pairs of shoes so that's .30 * 80 = 24 pair of shoes she donates. She had 80 shoes in her collection and donates 24 so that leaves 80 - 24 = 56 pairs of shoes. She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56 + 6 = 62 pairs of shoes. The answer is 62.

[Question]Each bird eats 12 beetles per day, each snake eats 3 birds per day, and each jaguar eats 5 snakes per day. If there are 6 jaguars in a forest, how many beetles are eaten each day?
[Answer]First find the total number of snakes eaten: 5 snakes / jaguar * 6 jaguars = 30 snakes. Then find the total number of birds eaten per day: 30 snakes * 3 birds / snake = 90 snakes. Then multiply the number of snakes by the number of beetles per snake to find the total number of beetles eaten per day: 90 snakes * 12 beetles / snake = 1080 beetles. The answer is 1080.

[Question]There are 14 green papayas on the papaya tree. On Friday, two of the fruits turned yellow. On Sunday, twice as many fruits as on Friday turn yellow. How many green papayas are left on the tree?
