Step-by-step reasoning process: Initially, Louise's cart has toys worth 10 * 28 = 280 dollars. If Louise pays for the toys originally in her cart, her wallet will remain with 580 - 280 = 300 dollars. Dividing the remaining amount by the number of teddy bears gives 300 / 20 = 15 dollars.
The question and answer:
Question and answer: Louise is in a toy store. She already has 28 toys worth $10 each in her cart. On her way to the till she adds 20 teddy bears to the cart. If the $580 in Louise's wallet is exactly enough to pay for all the toys, how much does each teddy bear cost?
The answer is 15

Step-by-step reasoning process: He writes 30 / 3 = 10 normal letters. Each letter is 20 / 10 = 2 pages. So that is 2 * 10 = 20 pages. His long letter takes 2 * 10 = 20 minutes per page. So it is 80 / 20 = 4 pages. So he writes 20 + 4 = 24 pages.
The question and answer:
Question and answer: Steve writes a letter every 3rd day to his friend. He spends 20 minutes writing the letters. It takes 10 minutes to write 1 page. He also writes a long letter at the end of the month which he puts more thought into. It takes twice as long per page but he spends 80 minutes writing. How many pages does he write a month?
The answer is 24

Step-by-step reasoning process: 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 question and answer:
Question and answer:
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.
The answer is 3600
