Answer:
Step-by-step explanation:
Alright, lets get started.
Suppose car was driven x miles in its 4 days trip.
Cost of a car rental is thirty dollar per day.
So, for 4 days, the car rental will be =
$
For 1 mile, it adds fifteen cents,
So, for x miles, the cost will be =
$
As per question, total rent is 180 $
Total rent will be =
Subtracting 120 in both sides
![0.15 x = 180-120=60](https://tex.z-dn.net/?f=0.15%20x%20%3D%20180-120%3D60)
![x=\frac{60}{0.15}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B60%7D%7B0.15%7D)
![x=400](https://tex.z-dn.net/?f=x%3D400)
It means car was driven 400 miles. : Answer
