In 2006, about 6 billion gal of renewable fuels, such as ethanol and other biofuels, were used in the united states. the energy law passed in 2007 requires that 48 billion gal of such fuels be used by 2023. what is the percent of increase?

The percentage increase of fuel amount by 2023 = 700 %

Step-by-step explanation:

Given as ,

The amount of renewable fuels, used in US in 2006 = 6 billion gallon

The amount of renewable fuels, to be used by 2023 = 45 billion gallon

∴ The percentage increase = × 100

I.e % increase = [tex]\frac{(48 - 6)}{6} × 100

Or, % increase = [tex]\frac{(42)}{6} × 100

Hence % increase = 700

So, The percentage increase of fuel amount by 2023 = 700 %   Answer
