[Question]John sublets his apartment to 3 people who each pay $400 per month. He rents the apartment for $900 a month. How much profit does he make in a year?
[Answer]He gets 3 * $400 = $1200 per month. So he gets 1200 * 12 = $14,400 per year. So he pays 12 * 900 = $10800 a year. That means his profit is 14400 - 10800 = $3600 per year. The answer is 3600.
Q: Yvette wants to frame a new picture. When she goes to her local frame shop, she finds out that the frame she wanted is 20% more expensive than her budget of $60. If she paid for a smaller frame at 3/4 the new price of the frame she initially intended to buy, how much money did she remain with?
A: The frame she initially intended to buy was 20 / 100 * $60 = $12 more expensive than she had thought. This means the frame was being sold at $60 + $12 = $72. If she paid for a smaller frame at 3 / 4 the price of the frame she initially intended to buy, she paid 3 / 4 * $72 = $54. Yvette remained with $60 - $54 = $6. The answer is 6.
Question: Miles and Daphne are comparing their reading collection and want to figure out who has more pages. They are about to count each page, but their parents suggest that they see whose collection is taller. Mile's collection is taller, but then Daphne notices that Miles reads board books, and so the pages are thicker. After some more measuring, they figure out that for Miles, 1 inch equals 5 pages, but for Daphne 1 inch equals 50 pages. If Miles's books are 240 inches tall and Daphne's collection is 25 inches tall, how many pages are in the longest collection?
Answer: Miles's collection has 1,200 pages because 240 x 5 = 1,200. Daphne's collection has 1,250 pages because 25 x 50 = 1,250. The largest collection has 1,250 pages because 1,250 > 1,200. The answer is 1250.
[Question]Tom decides to make lasagna with all his beef. It takes twice as many noodles as beef. He has 10 pounds of beef. He already has 4 pounds of lasagna noodles and the noodles come in 2-pound packages. How many packages does he need to buy?
[Answer]He needs 10 * 2 = 20 pounds of noodles. That means he needs to buy 20 - 4 = 16 pounds of noodles. So he needs to buy 16 / 2 = 8 packages. The answer is 8.
Q: Anthony keeps a bottle of vinegar in his cupboard for 2 years. Each year 20% of the vinegar evaporates. What percent of the vinegar is left after 2 years?
A: First find what percent of the vinegar is still in the bottle after each year: 100% - 20% = 80%. Then multiply the amount of vinegar left after one year by the percentage left after each year to find how much is left after 2 years: 80% * 80% = 64%. The answer is 64.
