We know that

• The company charges $19.95 plus $0.19 for each mile driven.

,

• Dana just has $50 to spend.

Based on the given information, we can define the following expression


19.95+0.19x\leq50

Then, we solve for x


\begin{gathered} 0.19x\leq50-19.95 \\ 0.19x\leq30.05 \\ x\leq(30.05)/(0.19) \\ x\leq158.2 \end{gathered}

Hence, the maximum number of miles Dana can drive is 158.
