Question: A washing machine uses 20 gallons of water for a heavy wash, 10 gallons of water for a regular wash, and 2 gallons of water for a light wash per load of laundry. If bleach is used, there is an extra light wash cycle added to rinse the laundry thoroughly. There are two heavy washes, three regular washes, and one light wash to do. Two of the loads need to be bleached. How many gallons of water will be needed?
Answer: Step-by-step reasoning process: The two heavy washes will use 20 * 2 = 40 gallons of water. The three regular washes will use 10 * 3 = 30 gallons of water. The light wash will use 2 * 1 = 2 gallons of water. The two bleached loads will use an extra 2 * 2 = 4 gallons of water. In all, 40 + 30 + 2 + 4 = 76 gallons of water will be needed.
So the answer is 76.

Question: It's field trip month, and the students took six vans and four minibusses. There were 10 students on each van and 24 students on each minibus. How many students went on the field trip?
Answer: Step-by-step reasoning process: The total number of students who took the van is 6 x 10 = 60. The total number of students who took the minibus is 4 x 24 = 96. Therefore, 60 + 96 = 156 students went on the field trip.
So the answer is 156.

Question: Sabrina gave 10 cookies to her brother. Her mother gave Sabrina half the number of cookies she gave her brother. Then Sabrina gave two-thirds of her cookies to her sister. If Sabrina had 20 cookies at the start, how many cookies are left with her?
Answer: Step-by-step reasoning process: Sabrina had 20 - 10 = 10 cookies left after giving 10 cookies to her brother. Sabrina's mother gave her 10 / 2 = 5 cookies. So, she had 10 + 5 = 15 cookies then. She gave 15 x 2 / 3 = 10 cookies to her sister. Therefore, she only has 15 - 10 = 5 cookies left.
So the answer is 5.

Question: A hardware store sold 10 graphics cards, 14 hard drives, 8 CPUs, and 4 pairs of RAM in one week. The graphics cards cost $600 each, hard drives cost $80 each, CPUs cost $200 each, and RAM cost $60 for each pair. How much money did the store earn this week?
Answer:
Step-by-step reasoning process: It earned 10 * 600 = 6000 dollars by selling graphics cards. It earned 14 * 80 = 1120 dollars by selling hard drives. It earned 8 * 200 = 1600 dollars by selling CPUs. It earned 4 * 60 = 240 dollars by selling RAM. Overall it earned 6000 + 1120 + 1600 + 240 = 8960 dollars this week.
So the answer is 8960.
