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 $550:000: with expenses of $15:000 per year for the first 20 years and $25:000 per year thereafter. Skyline also requires an expenditure of $210:000 twenty years after the initial investment and this will repeat every 20 years thereafter. The second plan (Prairie View) has an initial investment of $700:000 followed by a single (one-time) investment of $290:000 thirty years later. Prairie View will incur annual expenses of $9,000 forever. Based on the CW measure, which plan would you recommend?
