To determine how many times as much water was added to the cooler, you can find the difference between the final amount (22.1 liters) and the initial amount (5.2 liters), and then divide the final amount by the initial amount. Here are the steps:
Find the difference between the final amount and the initial amount:
22.1 liters−5.2 liters=16.9 liters
To find how many times as much water was added, divide the final amount by the initial amount:
16.9 liters /5.2 liters ≈ 3.25
So, approximately 3.25 times as much water was added to the cooler to bring the total amount to 22.1 liters.
