You have $45
After discount the fixed $5 and the charge for tolls, $45 - $5 - $5 = $35 are left.
1 mile cost $0.70. To find how many miles you can travel with $35, we can use the next proportion:
[tex]\frac{0.70\text{ \$}}{35\text{ \$}}=\frac{1\text{ mile}}{x\text{ mile}}[/tex]Solving for x
[tex]\begin{gathered} 0.70\cdot x=1\cdot35 \\ x=\frac{35}{0.70} \\ x=50\text{ miles} \end{gathered}[/tex]You can travel 50 miles from the airport
