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 9% per year. You have been asked to compare the two plans using the CW method. The first plan (Skyline) calls for an initial investment of $500,000, with expenses of S 15,000 per year for the first 20 years and $25,000 per year thereafter. Skyline also requires an expenditure of S200,000 twenty years after the initial investment, and this will repeat every 20 years thereafter. The second plan (Prairie View) has an initial investment of $750,000 followed by a single (one-time) investment of $300,000 thirty years later, Prairie View will incur annual expenses of $11,000 forever. Based on the CW measure, which plan would you recommend
