Q: A jug needs 40 cups of water to be full. A custodian at Truman Elementary School has to fill water jugs for 200 students, who drink 10 cups of water in a day. How many water jugs will the custodian fill with cups of water to provide the students with all the water they need in a day?
A: Since each student needs 10 cups of water per day and there are 200 students, the custodian has to provide 200 * 10 = 2000 cups of water. A jug of water needs 40 cups to be full, so 2000 cups of water will fill 2000 / 40 = 50 jugs. The answer is 50.

Q: There are 92 students altogether. Twenty of them ride the school bus home together, 5/8 of the remaining ride their own bike home, and the rest whose houses are near the school walk home. How many students are walking home?
A: If there are 92 students and 20 students take the bus home, the number of students who haven't taken the bus is 92 - 20 = 72 students. 5 / 8 of the students who didn't take the bus home ride bikes home, a total of 5 / 8 * 72 = 45 students. The number of students who neither took the bus nor biked home but walked home is 72 - 45 = 27. The answer is 27.

Q: Michonne is inviting her friends to her birthday party. She invites 6 of her friends from school and 12 of her friends from her neighborhood. Each of her friends asks if they can bring two friends along as well. How many people are going to Michonne’s birthday party?
A:
Michonne has invited 6 + 12 = 18 friends. These friends have invited another 18 friends * 2 = 36 people. So in total, there are 18 friends + 36 people = 54 people going to Michonne’s party. The answer is 54.
