Question: Santana has 7 brothers. 3 of them have birthdays in March, 1 of them has a birthday in October, 1 has a birthday in November, and another 2 of them were born in December. If Santana always buys each of her brothers a birthday present and a Christmas present, how many more presents does she have to buy in the second half of the year than the first half of the year?
Answer: Santana has 1 + 1 + 2 = 4 brothers with birthdays in the second half of the year. She has 7 brothers - 4 brothers = 3 brothers with birthdays in the first half of the year. Altogether, she has to buy 4 + 7 = 11 presents in the second half of the year. Therefore, she has to buy 11 - 3 = 8 more presents in the second half of the year. The answer is 8.
[Question]Mark went to a store where he spent one-half of his money, and then spent $14 more. He then went to another store where he spent one-third of his starting money, and then spent $16 more. If he then had no money left, how much did he have when he entered the first store?
[Answer]Let X be the money Mark had. Mark spent 1 / 2 * X + 14 in the first store and 1 / 3 * X + 16 in the second store. Mark has X - 1 / 2 * X - 14 - 1 / 3 * X - 16 = $0 left. Combining like terms, we get 1 / 6 * X - 30 = $0. Adding 30 to both sides and multiplying both sides by 6, we find that Mark had X = $180 when he entered the first store. The answer is 180.
Q: A class has 60 students. The number of students who bring their lunch is thrice the number of those who eat in the school cafeteria. The rest of the students don't eat lunch. If 10 students eat in the school cafeteria, how many don't eat lunch?
A: Multiplying the number of students eating at the cafeteria by three means that 3 * 10 = 30 students bring lunch. The total number of students that eat lunch is 10 + 30 = 40 students. Since the class has 60 students, those who don't eat lunch are 60 - 40 = 20 students. The answer is 20.
Question: James buys a jar of hot sauce. Each serving is .5 ounces. He uses 3 servings every day. if the container is 2 ounces less than 1 quart how many days will it last?
Answer: A quart is 32 ounces so this jar is 32 - 2 = 30 ounces. James uses 3 * .5 = 1.5 ounces a day. So it last 30 / 1.5 = 20 day. The answer is 20.
[Question]Samira is the assistant coach of a soccer team playing against one of the best teams in their league. She has four dozen water bottles filled with water in a box. In the first break of the match, the 11 players on the field each take two bottles of water from Samira's box, and at the end of the game, take one more bottle each. How many bottles of water are remaining in Samira's box?
[Answer]If the box has four dozen bottles of water, there are 4 * 12 = 48 bottles of water in the box. After the first half, the 11 players take 11 * 2 = 22 bottles of water from the box. If they take 11 more bottles of water at the end of the game, the number increases to 22 + 11 = 33 bottles of water taken. Without the bottles taken, there are 48 - 33 = 15 bottles of water remaining in the box. The answer is 15.
