Question: There are some kids in camp. Half of the kids are going to soccer camp, and 1/4 of the kids going to soccer camp are going to soccer camp in the morning. 750 kids are going to soccer camp in the afternoon. How many kids there in camp altogether?
Answer: There are 750 / 3 = 250 kids going to soccer camp in the morning. There are 250 * 4 = 1000 kids going to soccer camp altogether. There are 1000 * 2 = 2000 kids in camp altogether. The answer is 2000.
[Question]Some students want to buy pencils from a stationery shop. The price of one pencil is 20 cents. Tolu wants 3 pencils, Robert wants 5 pencils and Melissa wants 2 pencils. How much (in dollars) will the students spend altogether at the stationery shop?
[Answer]The three students want a total of 3 + 2 + 5 = 10 pencils. Each pencil cost 20 cents so 10 pencils cost 20 * 10 = 200 cents. 100 cents make a dollar so 200 cents make 200 / 100 = 2 dollars. The answer is 2.
Q: A passenger train transports passengers between two stations located in two separate cities. On a particular day, the train carried 100 passengers from one station to the other one way, and on the return trip carried 60 passengers. If the train made three more round trips that day, taking the same number of people as the first trip in each trip, calculate the total number of passengers transported between both stations?
A: The total number of people transported in the first trip is 100 one way + 60 on the return trip = 160 people. If the train made three more round trips that day carrying the same number of passengers in each trip as the first, it carried a total of 3 * 160 = 480 in all three round trips. In total, the train carried 160 + 480 = 640 people over all its trips that day. The answer is 640.
Question: Lucille is painting her room. Two of her walls are 3 meters wide and 2 meters tall. The third wall is 5 meters wide and 2 meters tall. The final wall is 4 meters wide and 2 meters tall. If each can of paint covers 2 square meters, how many cans of paint does Lucille need?
Answer: For the first set of walls, each wall covers 3 meters wide * 2 meters tall = 6 square meters. There are two of these walls, so this becomes a total of 6 meters * 2 walls = 12 square meters. The third wall covers 5 meters wide * 2 meters tall = 10 square meters. The final wall covers 4 meters wide * 2 meters tall = 8 square meters. So in total, the paint needs to cover 12 + 10 + 8 = 30 metres. Since each can covers 2 meters, Lucille needs 30 meters / 2 = 15 cans of paint. The answer is 15.
[Question]Karen had the giant box of crayons, containing twice as many crayons as were in Beatrice's box. But Beatrice's box contained twice as many crayons as were in Gilbert's box of crayons. And Gilbert had four times as many crayons as were in Judah's box of crayons. If Karen's box contained 128 crayons, how many crayons were in Judah's box?
[Answer]If Karen's 128 crayons were twice as many as were in Beatrice's box, there were 128 / 2 = 64 crayons in Beatrice's box. And since Beatrice's box contained twice as many crayons as were in Gilbert's box of crayons, then Gilbert had 64 / 2 = 32 crayons. And since Gilbert had four times as many crayons as Judah, then Judah had 32 / 4 = 8 crayons. The answer is 8.
[Question]Joe and Adam built a garden wall with three courses of bricks. They realized the wall was too low and added 2 more courses. If each course of the wall had 400 bricks, and they took out half of the bricks in the last course to allow easy checkup of the garden, calculate the total number of bricks the wall has.
[Answer]
When they added two more courses for the wall, the number of courses became 3 + 2 = 5. Since each course has 400 bricks, the total number of bricks for 5 courses is 5 * 400 = 2000. To allow for an easy checkup of the wall, they removed 1 / 2 * 400 = 200 bricks from the last course of the wall. In total, the wall has 2000 - 200 = 1800 bricks. The answer is 1800.
