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

Answer:

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%:

$x = \frac{2\% * 280 gallons}{100\%}$  // % 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.

Answer 2

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
