conversations.value: I would love to understand how to solve this problem: 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?
  Can you explain?

conversations.value: 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
