(B) What are two problems with using this rotation age to manage forest lands? CI Will this rotation age be longer or shorter than the rotation age that makimizes the present value of the total timber income over multiple rotations? Why?

2. A municipal solid-waste site for a city must be located at Site A or SiteB. After sorting, some of the solid wastes will be transported to an electric power plant where it will be used as fuel. Data for the hauling of solid wastes from each site to the power plant are shown in Table below. Average hauling distance Yearly rental fee for solid - SITE A 4 kilometers P5,000 SITE B 3 kilometers P100,000 waste site Hauling Cost P1.50 per m - km P1.50 per m - I n° - km If the power plant will pay P8.00 per m of sorted solid waste delivered to the plant, where should the solid-waste site be located? Use the city's viewpoint and assume that 200,000 m of wastes will be hauled to the plant for one year only. What site must be selected? Show your computation and defend your answer. (20 points)

1-26 A farmer must decide what combination of see water, fertilizer, and pest control will be most pro itable and environmentally conscious for the comi G year. The local agricultural college did a study of this farmer's situation and prepared the following table. Direct Extra-market Plan Cost/Acre Cost/Acre Income/Acre A $750 $150 $1200 В 800 450 1400 C 1000 250 1500 D 1300 200 1650 The last page of the college's study was torn off, and hence the farmer is not sure which plan the agri- cultural college recommends. Which plan should the farmer adopt considering: (a) only the direct costs, (b) both the direct and extra-market costs?
