Answer the following question.
The seats of a bus are arranged in 23 rows of 4 seats. At the start, 16 people climb. At the first stop, 15 people board the bus and 3 get off. At the second stop, 17 people get on the bus and 10 get off. How many empty seats are there after the second stop?
Step-by-step reasoning process: There are 23 * 4 = 92 seats on this bus. After the first stop, there are 16 + 15 - 3 = 28 people on the bus. After the 2nd stop, there are 28 + 17 - 10 = 35 people on the bus. So there are 92 - 35 = 57 empty seats on the bus after the 2nd stop.
The answer is 57.

Answer the following question.
Coral is reading a book that is 600 pages long. She reads half of it in the first week, and 30 percent of the remaining pages the second week. How many pages must she read the third week in order to finish the book?
Step-by-step reasoning process: Week 1:600 / 2 = 300. 600 - 300 = 300 pages remain. Week 2:300(.30) = 90 pages. 300 - 90 = 210 pages remain. Week 3:210 pages.
The answer is 210.

Answer the following question.
In a Math competition, Sammy scored 20 points, Gab scored twice as many as Sammy's score, while Cher scored twice as many as Gab's score. If their opponent scored 85 points, how many more points do they have than their opponent?
Step-by-step reasoning process: Gab scored 20 x 2 = 40 points. Cher scored 40 x 2 = 80 points. Their team scored 20 + 40 + 80 = 140 points. Therefore, they scored 140 - 85 = 55 more points than their opponent.
The answer is 55.
