Determine the total revenue with the new toll. Therefore, the new revenue will be:

A toll bridge carries 6,000 veh/day. The current toll is $3.50/vehicle. Studies have shown that for each increase in toll of 50 cents, the traffic volume will decrease by 500 veh/day. It is desired to increase the toll to a point where revenue will be maximized.

What will be an ideal response?


R = V × T
R = 4750 × (350 + 125)
R = 4750 × 475
R = 2,256,250 cents
R = $22,562.50
The total revenue to be generated with the new toll will be $22,562.50 per day.
Therefore, the increase in revenue would be:
Rnew – Rold = $22,562.50 - $21,000 = $1,562.50
