[Question]A school has 15 classrooms. One-third of these classrooms have 30 desks in each classroom and the rest have 25 desks in each classroom. Only one student can sit at one desk. How many students can this school accommodate so that everyone has their own desk?
[Answer]One - third of the classrooms have 30 desks, so there are 1 / 3 * 15 = 5 classrooms like that. The rest, which means 15 - 5 = 10 classrooms, have 25 desks. One - third of the classrooms can fit 5 * 30 = 150 students. The rest can fit 10 * 25 = 250 students. So in total, the school can be filled with 150 + 250 = 400 students. The answer is 400.
Q: Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?
A: First find the total distance Carson walks along the warehouse's long sides: 600 feet / side * 2 sides = 1200 feet. Then find the total distance Carson walks along the warehouse's short sides: 400 feet / side * 2 sides = 800 feet. Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 2000 feet. Then find the number of circles Carson actually walks: 10 circles - 2 circles = 8 circles. Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet / circle * 8 circles = 16000 feet. The answer is 16000.
Question: Randy had $3,000. Smith gave him another $200. Randy then gave Sally $1,200 and kept the rest. What was the value, in dollars, of the rest?
Answer: After Smith gave him $200, Randy had 3000 + 200 = 3200 dollars. The value of the rest of the money is 3200 - 1200 = 2000 dollars. The answer is 2000.

Question: Stan can type 50 words per minute. He needs to write a 5-page paper. Each page will contain 400 words. Each hour that he types he needs to drink 15 ounces of water. How much water does he need to drink while writing his paper?
Answer:
Stan needs to write 2,000 words because 5 x 400 = 2,000. This will take him 40 minutes because 2,000 / 50 = 40. He drinks 1 / 4 an ounce per minute because 15 / 60 = 1 / 4. He will drink 10 ounces of water while writing the paper because 40 x (1 / 4) = 10. The answer is 10.
