We first must find the difference between the two prices. So let's subtract:
![$89.38-82=7.38](https://img.qammunity.org/2019/formulas/mathematics/middle-school/mejzponlc6lrm4ge3um8oy3a13io9siloz.png)
Now we take this difference and divide it by the original amount that the price was:
![(7.38)/(82) =0.09](https://img.qammunity.org/2019/formulas/mathematics/middle-school/codrblwrf19i2ld5licquratt813o8k505.png)
This is the decimal form of the answer. In order to make it a percent, we must multiply it by 100:
![0.09*100=9](https://img.qammunity.org/2019/formulas/mathematics/middle-school/1zmz1ogmkpida2xfv7yunm6zi6nlhcmjqa.png)
So the percent change in this price is 9%.
