Question

gas prices in new york average $ 3.350per gallon in October 2021 ,up from 2.163 per gallon in October 2020. calculate the precent increase.

Answer 1

The percent increase formula is :

$\%=\frac{N-O}{O}\times100$

where N is the new price and O is the orignal price

From the problem, N = $3.35 and O = $2.163

Using the formula above :

$\%=\frac{3.35-2.163}{2.163}\times100=54.88\%$

The answer is 54.88%
