Hi!

The answer is 274.4 gallons of water remain to be used.

Step-by-step explanation:

You can use the Rule of three to solve this problem.

     100% ----> 280 gallons  // If 100% is 280 gallons

     2% ----> x gallons  // then 2% would be x gallons.

Now, multiply 2% by 280 gallons and divide the result by 100%:

 // % divided by % is 1.

gallons losted as steam.

To calculate the gallons remain to be used:

280 gallons - 5.6 gallons = 274.4 gallons.
