[Question]A class of 30 high school students is preparing for a field trip. If each student contributes $2 every Friday for their trip, how many dollars will they have in 2 months?
[Answer]They save 30 students * $2 / student / week = $60 / week. They saved for 2 months which is 2 months * 4 weeks / month = 8 weeks. So in 2 months, they will have $60 / week * 8 weeks = $480. The answer is 480.
Q: Michael has a chicken farm. His chickens increase in number by 150 chickens annually. If the number of chickens on his farm now is 550, how many will he have after 9 years?
A: The number of the increase in chicken after 9 years is 150 * 9 = 1350. So the total number of the chicken in Michael's farm will be 550 + 1350 = 1900. The answer is 1900.
Question: A man used to have 39 cows but last year 25 of them died and he sold 6 of them. This year the number of the cows increased by 24 and the man bought 43 more. His friend gave him 8 cows as a gift. How many cows does the man have now?
Answer: Last year he had 39 cows - 25 cows - 6 cows = 8 cows. This year after the number of the cows has increased he has 8 cows + 24 cows = 32 cows. After he bought more cows he now has 32 cows + 43 cows = 75 cows. After his friend gave him cows he now has 75 cows + 8 cows = 83 cows. The answer is 83.
[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.
Q: Steve's new book sells 1,000,000 copies. He got an advance to pay for 100,000 copies. He gets $2 for each copy of the book sold. His agent takes 10% of that. How much money did he keep not counting the money from the advance?
A: He sold 1,000,000 - 100,000 = 900,000 not counting the advance. So he made 900,000 * 2 = $1,800,000 from selling the books. His agent took 1,800,000 * .1 = $180,000. That means he kept 1,800,000 - 180,000 = $1,620,000. The answer is 1620000.
Question: Barbie enjoys buying jewelry. One day, she bought 12 pairs of earrings, and gave half of them to Alissa, making Alissa's total number of collections to be triple the number of earrings she was given. How many earrings does Alissa have now?
Answer:
If 1 pair of earrings equals 2 earrings, then Barbie bought 12 * 2 = 24 earrings. Half of 24 earrings is 24 / 2 = 12 earrings. If receiving 12 earrings tripled Alissa's collection, then she now has 12 * 3 = 36 earrings. The answer is 36.
