By what percentage did the gas price increase?
Type of calculation: Calculating percentage change (increase).
Calculator usage: Use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the original price as "Original" (2.00) and the new price as "New" (2.20).
Explanation using a formula:
We are looking for the percentage change from $2.00 to $2.20.
Formula: ((New value - Original value) / Original value) * 100%
Percentage change = (($2.20 - $2.00) / $2.00) * 100% = ($0.20 / $2.00) * 100% = 0.1 * 100% = 10%
