Bilboa Freightlines, S.A. of Panama has a small truck that it uses for local deliveries. The truck is in bad repair and must be either overhauled or replaced with a new truck. The company has assembled the following information (Panama uses the U.S. dollar as its currency): If the company keeps and overhauls its present delivery truck, then the truck will be usable for eight more years. If a new truck is purchased, it will be used for eight years, after which it will be traded in on another truck.
