Suppose you are in charge of a toll bridge that costs essentially nothing to operate. the demand for bridge crossings (q) is given by p = 15 – (1/10) q. the number of bridge crossings if the toll price were set to zero (p = $0) is and the loss in consumer surplus (cs) associated with a bridge toll of $5 (p = $5) is
