[Question]Jackson had 20 kilograms of meat. He used 1/4 of the meat to make meatballs and used 3 kilograms of meat to make spring rolls. How many kilograms of meat are left?
[Answer]Jackson used 20 x 1 / 4 = 5 kilograms of meat to make meatballs. He had 20 - 5 = 15 kilograms of meat left. So 15 - 3 = 12 kilograms of meat are left. The answer is 12.
Q: Anna is making gingerbread cookies. She gives 6 of them red hats, 9 of them blue boots, and 3 of them both red hats and blue boots. What percentage of the gingerbread men have red hats?
A: The first step to find the total number of gingerbread men is to add the number with each decoration: 6 men + 9 men = 15 men. Then subtract the number of gingerbread men with both decorations to find the total number of gingerbread men: 15 men - 3 men = 12 men. Then divide the number of gingerbread men with red hats by the total number and multiply by 100% to express the answer as a percentage: 6 men / 12 men * 100% = 50%. The answer is 50.
Question: A herring has 40 oz of fat, an eel 20 oz, and a pike 10 more oz of fat than an eel. If Ellianna cooked and served 40 fish of each type, calculate how many ounces of fat she served.
Answer: Ellianna cooking 40 herrings with 40 oz of fat each gives her 40 * 40 = 1600 oz of fat. If Ellianna also cooked 40 eels with 20 oz of fat each, she got 40 * 20 = 800 0z of fat. All the herrings and eels together have a total fat content of 1600 + 800 = 2400 oz of fat. A pike, with 10 more oz of fat than an eel, has 10 + 20 = 30 oz of fat. Cooking 40 pikes gives 40 * 30 = 1200 oz of fat. Since Ellianna cooked all the fish, she had 1200 + 2400 = 3600 oz of fat in her serving. The answer is 3600.
[Question]A 750 ml bottle of spirits costs $30.00 and has 16 servings per bottle. Most restaurants will charge $8.00 for one serving. How much money does a restaurant make on a bottle of spirits?
[Answer]There are 16 servings in 1 bottle and they charge $8.00 per serving so that's 16 * 8 = $128.00. 1 bottle yields $128.00 and they spent $30.00 for the bottle so they make 128 - 30 = $98.00 on each bottle. The answer is 98.
Q: Emberly takes her mornings walks every day. If each walk takes her 1 hour covering 4 miles, and she didn't walk for 4 days in March, calculate the total number of miles she's walked.
A: In March, she walked for 31 - 4 = 27 days. If she walks for an hour a day, the total number of hours she'll walk in March is 27 days * 1 hour a day = 27 hours. If each walk is 4 miles, the number of miles she walked in March is 27 * 4 = 108 miles. The answer is 108.
Question: A farmer is checking his fields to make sure all of his crops are growing as they should. Rows of corn stalks should produce 9 corn cobs each, and rows of potatoes should produce 30 potatoes each. As he’s checking crop quality, he notices that there are more pests than usual and they have destroyed some of his crops. He thinks that half of his crops have been destroyed by the pests. If the farmer has 10 rows of corn stalks and 5 rows of potatoes, how many crops does the farmer still have?
Answer:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The farmer had a total of 10 rows of corn stalks * 9 corn cobs each = 90 corn cobs. He also had a total of 5 rows of potatoes * 30 potatoes each = 150 potatoes. This was a total of 90 corn cobs + 150 potatoes = 240 crops. Because pests destroyed half of his crops, he now has 240 crops * 0.5 = 120 crops. The answer is 120.
