Question

a water heater tank holds 280 gallons. Two percent of the water is lost as steam. How many gallons remain to be used?

Answer 1

274.4 gallons are remaining. You would need to find how many gallons of water was lost as steam. You would do 280*0.02, which is 5.6 gallons. Then, subtract 5.6 from 280, and you get 274.4

Answer 2

Hi!

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

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%:

`x = (2\% * 280 gallons)/(100\%)` // % divided by % is 1.

`x = 5.6` gallons losted as steam.

To calculate the gallons remain to be used:

280 gallons - 5.6 gallons = 274.4 gallons.
