Question: Kendall is counting her change. She has a total of $4 in quarters, dimes, and nickels. If she has 10 quarters and 12 dimes, how many nickels does she have?
Answer: Step-by-step reasoning process: The total money from the quarters is 10 * $0.25 = $2.50. The total money from the dimes is 12 * $0.10 = $1.20. The total money from the nickels is $4 - $2.50 - $1.20 = $0.30. The number of nickels Kendall has is $0.30 / $0.05 = 6 nickels.
So the answer is 6.

Question: The teacher decided to rewards his students with extra recess on report card day if they got good grades. Students normally get 20 minutes for recess. He told the students that every A got them 2 extra minutes of recess. Every B got them one extra minute. Every C got them zero extra minutes, but every D got them 1 less minute. When report cards came out there were 10 As, 12 Bs, 14Cs, and 5Ds. In total, how much recess would the students get that day?
Answer: Step-by-step reasoning process: The students have 20 minutes to start. They get 20 minutes added for the As because 10 times 2 equals 20. They get 12 minutes added for the Bs because 12 times 1 equals 12. They get no minutes added or subtracted for the Cs because 14 times 0 equals 0. They get 5 minutes taken away for the Ds because 5 times 1 equals 5. In total, they get 47 minutes of recess because 20 plus 20 plus 12 minus 5 equals 47.
So the answer is 47.

Question: There is a lot of dust in Susie's house. It takes her 2 hours to vacuum the whole house. She can vacuum each room in 20 minutes. How many rooms does she have in her house?
Answer: Step-by-step reasoning process: Susie spends 2 * 60 = 120 minutes vacuuming. Since she can vacuum each room in 20 minutes, she has 120 / 20 = 6 rooms in her house.
So the answer is 6.

Question: Adam goes to school every day. On Monday he had 6 lessons of 30 minutes each, and on Tuesday he had 3 lessons of 1 hour each. On Wednesday, Adam spent twice as much time at school as on Tuesday. How much time in total did Adam spend at school during these 3 days, in hours?
Answer:
Step-by-step reasoning process: On Monday Adam had 6 * 30 = 180 minutes of lessons, which is 3 hours. On Wednesday Adam spent twice as much time at school as on Tuesday, so he spent 2 * 3 = 6 hours at school. This means that during these three days Adam spent at school 3 + 3 + 6 = 12 hours.
So the answer is 12.
