![Discount=(35)/(100)x](https://img.qammunity.org/2021/formulas/mathematics/high-school/8gl43rq73dytunqr3lazwbxyo4lgkzxio1.png)
Amount saved in sale = $25
![0.35x=25](https://img.qammunity.org/2021/formulas/mathematics/high-school/v3u55v5c5gg2cyrcbibksc6pjtjguu0naq.png)
Divide both sides by 0.35.
![x=(25)/(0.35)](https://img.qammunity.org/2021/formulas/mathematics/high-school/7i5blpklhmgtyhc8dk13o2ss5od7m9s220.png)
![x=71.42857](https://img.qammunity.org/2021/formulas/mathematics/high-school/usgrfsyurhp7joa9ofbgcbhhwepp6oefx7.png)
![x\approx 71.43](https://img.qammunity.org/2021/formulas/mathematics/high-school/fd3wpcx7iirbe9fd4piqhuvjxuy9fqey9q.png)
Therefore, the regular price of the tennis shoes is $71.43.
