Q: In one of the building blocks at Oakland High there are 5 classes. Each class uses 2 whiteboards each and each whiteboard needs about 20ml of ink for a day's use. If ink costs 50 cents per ml, how much (in dollars) would it cost to use the boards for one day?
A: Each ml of ink costs 50 cents so 20 ml costs 20 * 50 = 1000 cents. There are 2 whiteboards in each class so each class needs 2 * 1000 cents = 2000 cents. There are five classes in the block so they all need 5 * 1 * 2000 cents = 10000 cents. 100 cents make a dollar so 10000 cents make 10000 / 100 = $100. The answer is 100.
Question: A clothing store has an inventory of 34 ties, 40 belts, 63 black shirts, and 42 white shirts. The number of jeans in the store is two-thirds of the sum of black and white shirts, and the number of scarves is half the number of the sum of ties and belts. How many more jeans are there than scarves?
Answer: The sum of black and white shirts is 63 + 42 = 105. The number of jeans in the store is (2 / 3) x 105 = 70. The sum of ties and belts is 34 + 40 = 74. The number of scarfs in the store is 74 / 2 = 37. There are 70 - 37 = 33 more jeans than scarfs in the store. The answer is 33.
[Question]The coach of a football team asked his players to do six laps of the field. The field is in the shape of a rectangle of length 100 m and width 50 m. What is the distance each player will run, in meters?
[Answer]One lap corresponds to the perimeter of a rectangle of 100 m length and 50 m width: 2 * 100 + 2 * 50 = 300 metres. Each player has to do six turns of the field, so runs 6 * 300 = 1800 meters. The answer is 1800.
Q: Eighty-five cans were collected. LaDonna picked up 25 cans. Prikya picked up twice as many times as many cans as LaDonna. Yoki picked up the rest of the cans. How many cans did Yoki pick up?
A: LaDonna = 25 cans. Prikya is twice as many as LaDonna = 2 * 25 = 50. Yoki picked up the rest 85 - 25 - 50 = 10. Yoki picked up 10 cans. The answer is 10.
Question: Michael has a lot of matchsticks at home and decides to use them to make miniature models. As he is about to start crafting, he has second thoughts and decides to only use half of his pile of matchsticks. He creates 30 matchsticks houses. If he has now used all of the matchsticks he intended to and each matchstick house uses 10 matchsticks, how many matchsticks did Michael have originally?
Answer: Michael has used a total of 30 matchstick houses * 10 matchsticks per matchstick house = 300 matchsticks. As he only used half of his collection for crafting, he must have originally had 300 matchsticks * 2 = 600 matchsticks. The answer is 600.

Solomon is 3 * Juwan so Juwan is 1 / 3 of Solomon = 66 / 3 = 22. Levi collected half of 22 = 11. Combined the boys collected 66 + 22 + 11 = 99 cans in all. The answer is 99.
