5 The city of Danville is considering building a second river crossing to improve traffic-flow in the downtown core at an estimated cost of $A. The annual maintenance costs of the crossing will be $B, but users will save $C per year due to reduced waiting time. In addition, accidents are expected to drop by 40% representing a property and medical savings of $D per year. The crossing is expected to handle traffic adequately over a 20-year period.
