# Your gas bill went up from $125 per month to$150 per month. What is the percent increase of your gas bill?

The amount of the increase is  ($150 -$125)  =  $25 . As a fraction of the original amount,$25  is                                   $25/$125 = 1/5 of the original amount . The increase was 1/5 . 1/5 means  1  divided  by  5. To change a fraction into a decimal, do the division:        1/5 =  1 divided by 5  =  0.20 . To turn a decimal into a percent, move the decimal point 2 spaces that way  ===> .                  0.20  =  20 %
Percentage increase= $\frac{150-125}{125} *100$ $\frac{25}{125} *100$ = 20%
