Jefferson County's Board of Representatives is considering the purchase of a site for a new sanitary landfill. The purchase price for the site is $250,000 and preparatory work will cost $44,400. The landfill would be usable for 10 years. The board hired a consultant, who estimated that the new landfill would cost the county $40,000 per year less to operate than the county's current landfill. The current landfill also will last 10 more years. For a landfill project, Jefferson County can borrow money from the federal government at a subsidized rate. The county's hurdle rate is only 4 percent for this project. Use Appendix A for your reference. (Use appropriate factor(s) from the tables provided.)
