[Question]A bottle of wine costs $20.00 today. When new tariffs are imposed in 2 months, the price of wine will increase by 25%. How much more expensive will 5 bottles of wine be in 2 months?
[Answer]Today, 5 bottles of $20.00 wine will cost 5 * 20 = $100.00. In 2 months there will be a 25% tariff on the 5 bottles of wine that cost $100.00 so that makes the 5 bottles .25 * 100 = $25.00 more expensive. The answer is 25.
Q: Steve bought $25 worth of groceries. He bought a gallon of milk for $3, two boxes of cereal for $3.5 each, 4 bananas for $.25 each, four apples that cost $.5 each and a number of boxes of cookies. The cookies cost twice as much per box as the gallon of milk. How many boxes of cookies did he get?
A: He spent $7 on cereal because 2 x 3.5 = 7. He spent $1 on bananas because 4 x .25 = 1. He spent $2 on apples because 4 x .5 = 2. He spent 13 on everything but the cookies because 3 + 7 + 1 + 2 = 13. He spent $12 on cookies because 25 - 13 = 12. Each box of cookies is $6 because 3 x 2 = 6. He bought 2 boxes of cookies because 12 / 6 = 2. The answer is 2.
Question: All people named Barry are nice, while only half of the people named Kevin are nice. Three-fourths of people named Julie are nice, while 10% of people named Joe are nice. If a crowd contains 24 people named Barry, 20 people named Kevin, 80 people named Julie, and 50 people named Joe, how many nice people are in the crowd?
Answer: If all people named Barry are nice, and the crowd contains 24 people named Barry, then 1 * 24 = 24 of these people are nice. If only half of people named Kevin are nice, and the crowd contains 20 people named Kevin, then 0.5 * 20 = 10 of these people are nice. If three - fourths of people named Julie are nice, and the crowd contains 80 people named Julie, then (3 / 4) * 80 = 60 of these people are nice. If 10% of people named Joe are nice, and the crowd contains 50 people named Joe, then 0.1 * 50 = 5 of these people are nice. In total, the crowd contains 24 + 10 + 60 + 5 = 99 people who are nice. The answer is 99.

Out of the 20 students, 20 x 1 / 4 = 5 students stayed in the classroom. While 20 - 5 = 15 students went to the playground. Out of these 15 students, 15 x 1 / 3 = 5 are boys. Therefore, 15 - 5 = 10 girl students from this class are in the playground. The answer is 10.
