Q: A laboratory needs flasks, test tubes, and safety gear to carry out its experiments. They were given a $325 budget for the month. They bought $150 worth of flasks, spent two-thirds of that amount on test tubes, and used half of the test tube cost on safety gear. How many dollars of their budget remained?
A: The laboratory spent 2 / 3 * 150 = 300 / 3 = $100 on test tubes. They spent a further 100 / 2 = $50 on safety gear. In all, they spent 150 + 100 + 50 = $300. Thus, 325 - 300 = $25 of the laboratory’s budget remained. The answer is 25.

[Question]Owen bred 21 turtles, and Johanna has 5 fewer turtles than Owen. After 1 month, Owen has twice as many turtles as before and Johanna loses half of her turtles and donates the rest to Owen. How many turtles did Owen have?
[Answer]Johanna had 21 turtles - 5 turtles = 16 turtles. After 1 month, Owen was left with 21 turtles * 2 = 42 turtles. After 1 month, Johanna was left with 16 turtles / 2 = 8 turtles. After Johanna's donation, Owen was left with 42 turtles + 8 turtles = 50 turtles. The answer is 50.
Q: Amanda has to sell 80 tickets in 3 days so she can make enough money to go on vacation. On the first day, she sells 5 of her friends 4 tickets each. On the second day she sells 32 tickets. How many tickets does she need to sell on the third day to meet her goal?
A: Amanda sells 4 tickets to 5 friends so she sells 4 * 5 = 20 tickets on her first day. On her second day, she sells 32 tickets for a total of 20 + 32 = 52 Tickets so far. Having 80 tickets as the goal, she needs to sell 80 - 52 = 28 Tickets on her last day. The answer is 28.
Question: In the fall, a tree drops a tenth of its initial quantity of leaves each day over the course of four days, then abruptly drops the rest on the fifth day. If it had 340 leaves before they started to fall, how many leaves does it drop on the fifth day?
Answer: The tree drops 340 / 10 = 34 leaves for each of the four days. Thus, it drops 34 * 4 = 136 leaves over the first four days. Therefore, it drops 340 - 136 = 204 leaves on the fifth day. The answer is 204.
Q: Ginger is weaving mats out of colored straw. Each mat takes 20 red straws, 30 orange straws, and half as many green straws as orange straws. How many straws does she need to make 10 mats?
A:
First find the number of green straws each mat needs: 30 orange straws / 2 orange straws / green straw = 15 green straws. Then find the total number of straws in each mat: 15 straws + 20 straws + 30 straws = 65 straws. Then multiply that number by the number of mats to find the total number of straws Ginger needs: 65 straws / mat * 10 mats = 650 straws. The answer is 650.
