Q: Sam invested $10,000 and earned 20% interest compounded for 3 years. He then invested more until he had three times as much invested. The next year, he got a 15% return on his investment. How much money does he have now?
A: 59616
Step-by-step reasoning process: After one year, Sam had $10,000 * 1.2 = $12,000. After two years, he had $12,000 * 1.2 = $14,400. After the third year, he had $14,400 * 1.2 = $17,280. He then invested more money until he had 3 * $17,280 = $51,840. The first year after that, he had $51,840 * 1.15 = $59,616.

Q: Tom decides to renovate a house. There are 3 bedrooms and each bedroom takes 4 hours to renovate. The kitchen takes 50% longer than each bedroom. The living room took twice as much time as everything else combined. How long did everything take?
A: 54
Step-by-step reasoning process: The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours.

Q: Mr. Sanchez found out that 40% of his Grade 5 students got a final grade below B. How many of his students got a final grade of B and above if he has 60 students in Grade 5?
A: 36
Step-by-step reasoning process: Since 40% of his students got below B, 100% - 40% = 60% of Mr. Sanchez's students got B and above. Thus, 60 x 60 / 100 = 36 students got B and above in their final grade.

Q: A school has 15 classrooms. One-third of these classrooms have 30 desks in each classroom and the rest have 25 desks in each classroom. Only one student can sit at one desk. How many students can this school accommodate so that everyone has their own desk?
A: 400
Step-by-step reasoning process: One - third of the classrooms have 30 desks, so there are 1 / 3 * 15 = 5 classrooms like that. The rest, which means 15 - 5 = 10 classrooms, have 25 desks. One - third of the classrooms can fit 5 * 30 = 150 students. The rest can fit 10 * 25 = 250 students. So in total, the school can be filled with 150 + 250 = 400 students.
