Question

in 2008, the gas crisis hit a peak! gas prices were $4.11 per gallon, on average. now in 2018 gas prices average $2.92. find the percent change and state whether is it an increase or decrease.

Answer 1

It is a decrease because it went down in cost.

To find percent:

Find difference from original amount to present amount.

So we do 4.11-2.92

=1.19

Now find the percent:

1.19/4.11 is about 28%

28% change.

Someone plz double check this answer.
