Use the Graphical MethodThe Green Company uses three grades of recycled paper, called grades A, B, and C, producedfrom scrap paper it collects. Companies that produce these grades of recycled paper do so asthe result of a single operation, so the proportion of each grade of paper is fixed for eachcompany. The Ecology Company process produces 1 unit of grade A, 2 units of grade B, and 3units of grade C for each ton of paper processed and charges $300 for the processing. TheEnvironment Company process produces 1 unit of grade A, 5 units of grade B, and 1 unit ofgrade C for each ton of paper processed and charges $500 for processing. The Green Companyneeds at least 100 units of grade A paper, 260 units of grade B paper, and 180 units of gradeC paper. How should the company place its order so that costs are minimized?
