Multiplying both side by 100
![2.5x = 1.60 * 100\\2.5x = 160](https://img.qammunity.org/2021/formulas/mathematics/middle-school/3xe3p9pukycjipfabgm8p43tjooi7m98ub.png)
Dividing both side by 2.5
![x = (160)/(2.5)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/42ybu42ly60qryn3mq0ymsv0cgdueqd6d7.png)
![x = 64](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8mef6hbtzx19holaezs83116c3ex1z241k.png)
Therefore, the price of Caleb’s groceries, before tax = $ 64
