The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
[tex]30-30+3x=174-30\\3x=144[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{144}{3}\\x=48[/tex]
The car was towed for 48 miles.
