[Question]James decides to build a tin house by collecting 500 tins in a week. On the first day, he collects 50 tins. On the second day, he manages to collect 3 times that number. On the third day, he collects 50 tins fewer than the number he collected on the second day. If he collects an equal number of tins on the remaining days of the week, what's the number of tins he collected each day for the rest of the week?
[Answer]On the second day, he collected 3 times the number of tins he collected on the first day, which is 3 * 50 = 150 tins. On the third day, he collected 50 tins fewer than the second day, which is 150 - 50 = 100 tins. The total for the three days is 150 + 100 + 50 = 300 tins. To reach his goal, he still needs 500 - 300 = 200 tins. Since the total number of days left in the week is 4, he'll need to collect 200 / 4 = 50 tins per day to reach his goal. The answer is 50.
Q: Karen is packing her backpack for a long-distance hike. She packs 20 pounds of water, 10 pounds of food, and 20 pounds of gear. During her hike, she drinks 2 pounds of water per hour and eats 1/3rd the weight of food per hour as water per hour. How much weight is she carrying after six hours?
A: First find the weight of food Karen eats every hour: 2 pounds * 1 / 3 = 2 / 3 pounds food. Then find the total amount of weight Karen's backpack loses per hour she hikes: 2 pounds water / hour + 2 / 3 pound food / hour = 8 / 3 pounds / hour. Multiply this by the number of hours she hikes to find the total amount of weight she loses: 8 / 3 pounds / hour * 6 hours = 16 pounds. Add the weight of all her items to find total starting weight: 20 pounds + 10 pounds + 20 pounds = 50 pounds. Then subtract the weight she loses from the starting weight to find the weight after 6 hours: 50 pounds - 16 pounds = 34 pounds. The answer is 34.
Question: A dietitian ate three-fourths of her lunch during her lunch break. If the total amount of food she had prepared for lunch had 40 calories, and the recommended calorie intake by the FDA is 25, how many more calories than the recommended amount did she eat?
Answer: A dietitian ate three - fourths of her lunch during her lunch break, containing 3 / 4 * 40 = 30 calories. If the recommended calorie intake by the FDA is 25, the dietitian ate 30 - 25 = 5 more calories than the recommended amount. The answer is 5.
[Question]Martin is organizing a party, and he invited many of his colleagues. He invited 5 people from his hometown and twice as many people from his school. Martin invited also as many people from his sports club as the sum of people invited from his hometown and his school. The remaining invitations represent 20% of the total previously mentioned. How many people can potentially come to the party Martin is organizing?
[Answer]Martin invited 5 * 2 = 10 people from his school. People from the sports club got 5 + 10 = 15 invitations. So in total from the sports club, hometown and school, Martin invited 5 + 10 + 15 = 30 people. All other invitations are 20% of the previous total, which means 20 / 100 * 30 = 6. That means Martin invited to his party 30 + 6 = 36 people. The answer is 36.
Q: Carrie is wrapping three birthday presents. One present needs two square feet of wrapping paper to cover. The second present needs three-quarters of that amount. The third present needs the same amount as both other presents put together. How many square feet of wrapping paper does Carrie need for all three presents?
A: The second present needs 3 / 4 * 2 = 1 1 / 2 square feet of wrapping paper. The third present needs 2 + 1 1 / 2 = 3 1 / 2 square feet of wrapping paper. Therefore, Carrie needs 2 + 1 1 / 2 + 3 1 / 2 = 7 square feet of wrapping paper for all three presents. The answer is 7.

If 1 carton contains 12 boxes, then a dozen cartons contain 12 * 12 = 144 boxes. If 1 box has 10 packs of cookies, then 144 boxes have 144 * 10 = 1440 packs. If a dozen cartons cost $1440 and contain 1440 packs of cookies, then each pack costs 1440 / 1440 = $1. The answer is 1.
