Q: Bill is a painter who is hired to paint a client’s house. The house has three bedrooms, and twice as many other rooms as bedrooms. The client wants each bedroom painted a different color, and the other rooms painted white. Each room takes 2 gallons of paint. Color paint comes in 1-gallon paint cans, and white paint comes in 3-gallon cans. How many cans of paint will Bill need for the whole house?
A: Bill needs 2 * 3 = 6 gallons of color paint for the 3 bedrooms. Thus, he needs 6 / 1 = 6 cans of color paint for the bedrooms. There are 2 * 3 = 6 other rooms in the house. He needs 2 * 6 = 12 gallons of white paint for the other rooms. Thus, he needs 12 / 3 = 4 cans of white paint. In all, Bill needs 4 + 6 = 10 cans of paint for the whole house. The answer is 10.

[Answer]Ellen ate 353 calories for breakfast + 885 for lunch + 130 for a snack = 1368 calories. Ellen has 2,200 calories – 1368 = 832 calories left for dinner. The answer is 832.
Q: How many cheese balls are in a 35oz barrel if the 24oz barrel has 60 servings and each serving has 12 cheese balls?
A: If 1 serving has 12 cheese balls, then 60 servings have 60 * 12 = 720 balls. If a 24oz barrel has 60 servings and we know that equates to 720 balls, then there are 720 / 24 = 30 balls in each oz. If 1 oz has 30 balls, then a 35oz barrel would have = 1050 cheese balls. The answer is 1050.
Question: Ali, Peter, and Joey were fishing. The fish Ali caught weighed, in sum, twice as much as the fish that Peter caught. Joey caught 1 kg more fish than Peter. Together the three of them caught 25 kg of fish. How many kilograms did Ali catch?
Answer:
Let x be the weight of the fish that Peter caught. Then Ali and Joey caught 2 * x and x + 1 kg of fish, respectively. So, x + 2 * x + x + 1 = 25. So, 4 * x = 25 - 1 = 24. So, x = 6. Therefore, Ali caught 2 * x = 2 * 6 = 12 kg of fish. The answer is 12.
