Consider the Q and A. Q: Part of Stella's job is to restock the toilet paper in each of the 6 bathrooms at the bed and breakfast. She stocks 1 roll a day, every day of the week. She buys the toilet paper in bulk, and each pack contains 1 dozen rolls. After 4 weeks, how many packs of toilet paper dozen Stella buy?
A: 14
What is the step-by-step reasoning process?
Step-by-step reasoning process: She stocks one roll in each of the 6 bathrooms, every day of the week so that 6 * 7 = 42 rolls a week. She restocks 42 rolls a week so after 4 weeks that's 42 * 4 = 168 rolls. The bulk toilet paper comes 1 dozen rolls in a pack and she needs 168 rolls so she needs 168 / 12 = 14 dozen.

Consider the Q and A. Q: Bob, Tom, Sally, and Jerry had dinner at their favorite pizzeria. They decide to share 2 pizzas. Bob ate half of a pizza on his own. Tom ate one-third of a pizza. Sally wasn't very hungry and only ate one-sixth of a pizza, and Jerry ate a quarter of a pizza. If each pizza is cut into 12 slices, how many slices were left over?
A: 9
What is the step-by-step reasoning process?
Step-by-step reasoning process: Each pizza is 12 slices. Bob at 12 slices / 2 = 6 slices. Tom ate one third, or 12 slices / 3 = 4 slices. Sally ate one sixth, or 12 slices / 6 = 2 slices. Jerry ate one quarter, or 12 slices / 4 = 3 slices. In total, they ate 6 slices + 4 slices + 2 slices + 3 slices = 15 slices. So they were left with 12 slices per pizza * 2 pizzas - 15 slices = 24 slices - 15 slices = 9 slices.

Consider the Q and A. Q: An opera house has 150 rows; each row has ten seats. The ticket costs $10 per show. How much did the opera house earn from one of the shows if 20% of the seats were not taken?
A: 12000
What is the step-by-step reasoning process?
Step-by-step reasoning process: The opera house has 150 x 10 = 1500 seats. There are 1500 x 20 / 100 = 300 seats that were not taken. The total number of seats taken was 1500 - 300 = 1200. Therefore, the opera house earned $10 x 1200 = $12000 from one of the shows.

Consider the Q and A. Q: Tom's rabbit can run at 25 miles per hour. His cat can run 20 miles per hour. The cat gets a 15-minute head start. In hours, how long will it take for the rabbit to catch up?
A: 1
What is the step-by-step reasoning process?
Step-by-step reasoning process:
The cat got a 15 / 60 = .25 hour head start. That means it ran 20 * .25 = 5 miles. The rabbit goes 25 - 20 = 5 mph faster than the cat. So it takes 5 / 5 = 1 hour for the rabbit to catch up.
