Answer this question:A farmer has twice as many pigs as cows, and 4 more cows than goats. If the farmer has 56 animals total, how many goats does he have?
Let x be the number of goats. Cows:4 + x. Pigs:2(4 + x) = 8 + 2x. Total:x + 4 + x + 8 + 2x = 56. 4x + 12 = 56. 4x = 44. x = 11 goats.
The answer is 11.

Answer this question:Oliver wonders how much water his bathtub can hold. So he takes a bucket that holds 120 ounces and starts filling the bathtub. When it reaches the top, he sees that he filled it 14 times. Then he wonders how much bathwater he uses, so he starts taking away buckets until it gets to the level he puts it at. He needs to take away 3 buckets to do this. Finally, he wonders how much water he uses in a week for his baths, which he takes every day. How much water does he use each week?
He uses 11 buckets to fill his bath normally because 14 - 3 = 11. He uses 1, 320 ounces a day for his baths because 11 x 120 = 1,320. He uses 9, 240 ounces a week for his baths because 7 x 1,320 = 9,240.
The answer is 9240.

Answer this question:A building has four floors with ten rooms each. Legacy has to clean each room, and it takes her 6 hours to clean one room. If she earns $15 per hour of work, calculate the total amount of money she makes from cleaning all the floors in the building.
Since the building has four floors with ten rooms each, the total number of rooms in the building is 4 * 10 = 40. If it takes Legacy 6 hours to clean each room, she will take 40 * 6 = 240 hours to clean all the rooms in the building. Since she is making $15 per hour of work, she will earn $15 * 240 = $3600 after cleaning all the rooms.
The answer is 3600.
