Q: Cooper is building a brick fence around all four sides of his property. Each of the four walls of his fence is 20 bricks long, 5 bricks high, and 2 bricks deep. How many bricks does Cooper need to complete his fence?
A: 800
Step-by-step reasoning process: A single layer of each wall requires 5 rows * 20 bricks per row = 100 bricks. As each wall has a thickness of 2 bricks, he will need 100 bricks * 2 = 200 bricks per wall. If the complete fence contains four walls, he will require a total of 200 * 4 = 800 bricks.


Q: John writes 20 pages a day. How long will it take him to write 3 books that are 400 pages each?

Q: Joe plays a soccer tournament with his team. Matches won score 3 points for the winning team and tied matches score 1 point for both teams. Joe and his team won 1 game and drew 3. The first-place team has won 2 games and tied 2. By how many points did the first-place team beat Joe's team?
A: 2
Step-by-step reasoning process: For 1 match won, Joe's team scored 1 * 3 = 3 points. For 3 tied games, Joe's team scored 3 * 1 = 3 points. In total, Joe's team scored 3 + 3 = 6 points. For 2 games won, the first - place team scored 2 * 3 = 6 points. For 2 tied games, the first - place team scored 2 * 1 = 2 points. In total, the first - place team scored 6 + 2 = 8 points. The first - place team outscored Joe's team by 8 - 6 = 2 points.

Step-by-step reasoning process: Mary spent 5 x $6 = $30 on drinks. She spent 10 x $14 = $140 on pizzas. She spent a total amount of $30 + $140 = $170. Therefore, Mary got a change of $200 - $170 = $30 after paying all the items for her pizza party.
