Consideration is being given to increasing the toll on a bridge now carrying 4500 veh/day. The current toll is $1.25/veh. It has been found from past experience that the daily traffic volume will decrease by 400 veh/day for each 25ยข increase in toll. Therefore, if x is the increase in toll in cents/veh, the volume equation for veh/day is V = 4500 - 400 (x / 25) , and the new toll/veh would be T = 125 + x. In order to maximize revenues, what would the new toll charge be per vehicle and what would the traffic in veh/day be after the toll increase?
What will be an ideal response?
