Explanation:
Let's set up an equation with some variables:
= hours of service
= total bill
![T=100h+250](https://img.qammunity.org/2021/formulas/mathematics/high-school/lt3xnl4mmet85s3ksgidielu5fni2q3qqn.png)
Plugging in our given values, we get:
![3500=100h+250](https://img.qammunity.org/2021/formulas/mathematics/high-school/l50jaajpkjtry98eez77a6j018zd2jykyh.png)
And solving for
, the hours the attorney worked, we get:
