Answer:
Total revenue by the toll bridge = $45
Step-by-step explanation:
Total vehicles crosses the bridge = 30
Number of passenger cars = 60 % of all vehicles = = 18
Other vehicles = 30 - 18 = 12
Charges for one passenger cars = $1.00
Thus total Revenue by the passenger cars = 18 × 1 = $18
Charges for other vehicles = $2.25
Total revenue by other vehicles = 2.25 × 12 = $27
Thus the total revenue from the toll bridge = 18 + 27 = $45
