The National Park Service is considering two plans for rejuvenating the forest and landscape of a large tract of public land. The study period is indefinitely long, and the Park Service’s MARR is 10% per year. You have been asked to compare the two plans using the CW method. The first plan (Skylin) calls for an initial investment of $500,000, with expenses of$20,000 per year for the first 20 years and $30,000 per year thereafter. Skyline also requires an expenditure of $200,000 20 years after the initial investment, and this will repeat every 20 years thereafter. The second plan (Prairie View) has an initial investment of $700,000 followed by a single (one time) investment of $300,000 30 years later. Prairie View will incur annual expenses of $10,000 forever. Based on the CW measure, which plan would you recommend?
