Question: John buys 3 boxes of burritos. He gives away a 3rd of them to his friend. Each box has 20 burritos. He eats 3 burritos per day for 10 days. How many burritos does he have left?
Answer: He gave 3 / 3 = 1 box away. So he has 3 - 1 = 2 boxes. So he got 2 * 20 = 40 burritos. He ate 3 * 10 = 30 burritos. So he has 40 - 30 = 10 burritos left. The answer is 10.

Question: Alan has 8 pine trees in his backyard and each tree drops 200 pine cones. If 30% of the pine cones fall on Alan's roof, and each pine cone weighs 4 ounces, how many ounces of pine cones does Alan have on his roof?
Answer: First find the total number of pine cones: 8 trees * 200 pine cones / tree = 1600 pine cones. Then multiply that number by 30% to find how many fall on Alan's roof: 1600 pine cones * 30% = 480 pine cones. Then multiply that number by the weight of each pine cone to find the total weight of the pine cones: 480 pine cones * 4 ounces / pine cone = 1920 ounces. The answer is 1920.

Question: Ella has 4 bags with 20 apples in each bag and six bags with 25 apples in each bag. If Ella sells 200 apples, how many apples does Ella has left?
Answer: 4 bags have 4 x 20 = 80 apples. And, six bags have 6 x 25 = 150 apples. Thus, Ella has 80 + 150 = 230 apples in all. Therefore, Ella has 230 - 200 = 30 apple left. The answer is 30.

Question: A movie theater has 6 screens which show movies back-to-back all day. If the movie theater is open for 8 hours, and each movie lasts 2 hours, how many movies are shown in total throughout the day?
Answer:
Each screen shows movies all day, which means each screen shows 8 hours / day / 2 hours per movie = 4 movies / day. So in total, the movie theater shows 6 screens * 4 movies / day = 24 movies. The answer is 24.
