Q: Carl types at a speed of 50 words per minute. If he types continuously for 4 hours per day, how many words can he type in 7 days?
A: The number of words that Carl can type per hour is 50 * 60 = 3000 words. The number of words that Carl can type in 4 hours is 3000 * 4 = 12000 words. The number of words that Carl can type in 7 days is 12000 * 7 = 84000 words. The answer is 84000.
Question: Adam goes to a small school, which teaches 80 students in three classes. 40% of the students are in class A, and class B has 21 students fewer than class A. The rest are in class C. How many students are in this class?
Answer: In class A, there are 40 / 100 * 80 = 32 students. In class B, the number of students is less by 21, which means class B has 32 - 21 = 11 students. That means 80 - 32 - 11 = 37 students are in class C. The answer is 37.

Question: Marly is making soup. He adds 2 quarts of milk and three times as much chicken stock to 1 quart of pureed vegetables. Then he divides the soup into bags that can hold 3 quarts each. How many bags does he need?
Answer: First triple the amount of milk to find the amount of chicken stock: 2 quarts * 3 = 6 quarts. Then add all three quantities to find the total volume of the soup: 6 quarts + 2 quarts + 1 quart = 9 quarts. Finally, divide the number of quarts by the number of quarts per bag to find the number of bags needed: 9 quarts / 3 quarts / bag = 3 bags. The answer is 3.
