Two routes are under consideration for new highway. The northerly route X would be located about 5 miles from the central business district and would require longer travel distance by local commuter traffic. The southerly route Y would pass directly trough the downtown area and, although its construction cost would be higher, it would reduce the travel time and distance for local commuter. Assume the cost for two route are as follow : Route X Route Y Initial cost Maintenance...
