My question is: 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? Your thoughts:
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 final answer: 50.
