We first must find the difference between the two prices. So let's subtract:
[tex] $89.38-82=7.38 [/tex]
Now we take this difference and divide it by the original amount that the price was:
[tex] \frac{7.38}{82} =0.09 [/tex]
This is the decimal form of the answer. In order to make it a percent, we must multiply it by 100:
[tex] 0.09*100=9 [/tex]
So the percent change in this price is 9%.
