From 6 am to 12 am - 18hrs
Vehicles per minute - 4
Vehicles per hour - 60×4 = 240
Therefore total number of vehicles passed - approx = 250×18 = 4500
Number of toll booths = 7
Money collected = 7×4500×0.75 = 23000$

We can create the expression:

7 tollbooths x $0.75 per vehicle x 4 vehicles per minute x 60 minutes x 18 hours = $22,680 ≈ $23,000
