Answer: Fuel prices jumped by %.

Type of calculation: Calculating percentage increase.
How to use the calculator: Use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter the old price 2.00 [Original] and the new price 2.20 [New].
The formula:
We want to find the percentage increase from $2.00 to $2.20.
Formula: ((New price - Old price) / Old price) × 100%
Percentage increase = (($2.20 - $2.00) / $2.00) × 100% = ($0.20 / $2.00) × 100% = 0.1 × 100% = 10%
