Find the percent change of 10 gallons to 24 gallons

140%

Step-by-step explanation:

To find the percentage change, find the difference between the two values and divide it by the original value. This will result in a decimal. To convert to a percentage multiply by 100.

So 24 - 10 = 14 gallon difference

Divide 14 / 10 = 1.4 change.

Multiply by 100, 100*1.4 = 140%.
