Question

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?

Answer 1

The percentage increase of fuel amount by 2023 = 700 %

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 =
`((final value - initial value))/(initial value)` × 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
