Question: Tommy is making steaks for his family. There are 5 of them in total. If each member wants one pound and the steaks are 20 ounces each, how many does he need to buy?
Answer with step-by-step thinking: He needs 80 ounces of steak because 5 x 16 = 80. He need 4 steaks because 80 / 20 = 4.
So the answer is 4.


Question: Matt wants to repaint his house. He needs to paint three walls in his living room, which is a square 40 feet by 40 feet, and all four walls in his bedroom, which is a rectangle 10 feet by 12 feet. All the walls in Matt's house are 10 feet tall. How many total square feet of wall does Matt need to paint?
Answer with step-by-step thinking: First figure out how many square feet a wall in the living room is: 40 feet length * 10 feet height = 400 square feet. Now multiply by 3 since Matt needs to paint three living room walls: 400 square feet / wall * 3 walls = 1200 square feet. Next figure out how many square feet the long walls in the bedroom are: 12 feet * 10 feet = 120 square feet. There are two long walls, so multiply this figure by 2: 120 square feet / wall * 2 walls = 240 square feet. Next figure out how many square feet the short walls in the bedroom are: 10 feet * 10 feet = 100 square feet. Multiply this by 2, since there are two short walls: 100 square feet / wall * 2 walls = 200 square feet. Finally, add up the square footage from the three living room walls, the two short bedroom walls, and the two long bedroom walls: 1200 square feet + 240 square feet + 200 square feet = 1640 square feet.
So the answer is 1640.


Question: Sabrina went to the library and found a historical series novel called The Rangers Apprentice. There are 14 books in the series, and each book has 200 pages. She read four books in a month and half the number of books remaining in the second month. What's the total number of pages Sabrina has to read to finish the whole series?
Answer with step-by-step thinking:
The total number of pages in the series is 14 books * 200 pages / book = 2800 pages. Sabrina read 4 books * 200 pages / book = 800 pages in the first month. She still has 14 books - 4 books = 10 books after reading four books. In the second month, she read 1 / 2 * 10 books = 5 books. The total number of pages she read is 5 books * 200 pages / book = 1000 in the second month. In total, Sabrina 1000 pages + 800 pages = 1800 pages in two months. Sabrina has to read 2800 pages - 1800 pages = 1000 more pages to complete the total series.
So the answer is 1000.
