Question and rationale: The question is: Donna worked 2 hours every morning walking dogs in her neighborhood for $10.00 an hour. 5 days a week, after school, she worked at a card shop for 2 hours and made $12.50 an hour. On the weekends, she usually made $10.00 an hour babysitting and was guaranteed 4 hours every Saturday from her neighbor. How much money did she make over 7 days?
Step-by-step reasoning process: She makes $10.00 an hour for 2 hours walking dogs so she makes 10 * 2 = $20.00 every morning. Over 7 days she makes 7 * 20 = $140.00 a week. She makes $12.50 for 2 hours working at a card shop so she makes 12.5 * 2 = $25.00. She works there 5 days a week so she makes 5 * 25 = $125.00 a week. She also babysits for 4 hours making $10.00 an hour for a total of 4 * 10 = $40.00. Over 7 days, she makes 140 + 125 + 40 = $305.00.

Question and rationale: The question is: One hundred chips were divided by Ian and Lyle in the ratio 4:6. What percentage of the chips did Lyle have?
Step-by-step reasoning process: The chips were divided into 4 + 6 = 10 parts. Each part has 100 / 10 = 10 chips. Since Lyle owns 6 parts, then he has 6 x 10 = 60 chips. This is 60 / 100 x 100 = 60% of the entire chips.

Question and rationale: The question is: A building has 10 floors. It takes 15 seconds to go up the stairs to the even-numbered floors and 9 seconds to go up to the odd-numbered floors. This includes getting to the first floor. How many minutes does it take to get to the 10th floor?
Step-by-step reasoning process: So for all even - numbered floors (2, 4, 6, 8, 10), it takes 5 * 15 = 75 seconds. And for all odd - numbered floors (1, 3, 5, 7, 9) it takes 5 * 9 = 45 seconds. To climb all the floors, it takes 75 + 45 = 120 seconds. So it takes 120 / 60 = 2 minutes to get to the 10th floor.

The question is: Martin is casting three bells for the church's belfry. The first bell takes 50 pounds of bronze, the second bell is twice the size of the first bell, and the third bell is four times the size of the second bell. How much bronze does he need total?
Step-by-step reasoning process: First find the size of the second bell: 50 pounds * 2 = 100 pounds. Then find the size of the third bell: 100 pounds * 4 = 400 pounds. Then add the amount of bronze used for each bell to find the total: 100 pounds + 400 pounds + 50 pounds = 550 pounds.
