Problem 2: [40 ppoints] The Regional Forest District manager proposes a new campsite for visitors at Largo Lake: it will cost $550,000 to build and $5000 per year to maintain it. a) If the interest rate is 1=6%, what would be the minimum value of perpetual annual benefits for this project to make sense (be feasible)? Show (explain) your work. [5points] The forest manager is unsure if the campsite will generate enough benefit to justify the investment so he commissions a study by an economic consulting company to estimate the potential demand for the campsite. As the campsite is only a proposal, the economic consulting company conducts a travel-cost study on the Corto Lake campsite, a campsite with similar characteristics in a neighboring forest region and serves a similar population base. The following survey data was collected on the visitors to the Corto Lake campsite during one year, to evaluate the demand on the site. No admission fee is currently charged at the Corto Lake campsite. Zone Zone population Average travel cost Visits per year from home to park 3000 10 1500 2 4800 15 1920 3 2000 25 400b) Using the information in the table above. fill out the table below that give the estimated number of visits per 1000 people for each zone and indicated travel costs? Interpolate as needed, and disregard fractions. Show all your working steps. [5 points] Zone $0 $5 $10 $15 $20 $25 $30 $35 2 Total 2
