Q: John decides to trade in his stereo system. His old system cost 250 dollars and he got 80% of the value for it. He then buys a system that costs $600 that he gets a 25% discount on. How much money came out of his pocket?
A: He got 250 * .8 = $200. He gets a 600 * .25 = $150 discount on the second system. So it cost 600 - 150 = $450. So he was 450 - 200 = $250 out of pocket. The answer is 250.
Question: In Carrie's desk drawer there are 7 yellow highlighters. There are 7 more pink highlighters than yellow highlighters, and there are 5 more blue highlighters than pink highlighters. How many highlighters are in Carrie's desk drawer in all?
Answer: The number of pink highlighters is 7 + 7 = 14. The number of blue highlighters is 14 + 5 = 19. There are 7 yellow highlighters. The total number of yellow, pink, and blue highlighters is 7 + 14 + 19 = 40. The answer is 40.
[Question]Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.
[Answer]Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish. The answer is 17.
Q: A bear is hunting for her cubs and herself. She needs 210 pounds of meat in a week. Each cub needs 35 pounds a week and she has 4 cubs. She hunts rabbits, which are five pounds each. If she hunts daily, how many rabbits does she need to catch each day?
A: The cubs need 140 pounds a week because 4 x 35 = 140. The family needs 350 pounds a week because 210 + 140 = 350. The family needs 50 pounds a day because 350 / 7 = 50. She needs to hunt 10 rabbits a day because 50 / 5 = 10. The answer is 10.
Question: Jorge and Giuliana each eat 7 croissants for breakfast, 18 cakes after school, and 30 pizzas before bedtime. What is the total number of croissants, cakes, and pizzas the two consume in a day?
Answer: The number of croissants and cakes that each eats for breakfast and lunch respectively is 7 + 18 = 25. After eating 30 pizzas before bedtime, the number of croissants, cakes, and pizzas that each person have in total for the day is 25 + 30 = 55. Since each person eats a total of 55 croissants, cakes, and pizzas for the day, the two consume a total of 55 + 55 = 110 of the food in a day. The answer is 110.
