The Sweet Smell Fertilizer Company markets bags of manure labeled "not less than 50 lb dry weight." The packaged manure is a combination of compost and sewage wastes. To provide good-quality fertilizer, each bag should contain at least 30 lb of compost but no more than 40 lb of sewage. Each pound of compost costs Sweet Smell 5 and each pound of sewage costs 6 the objective The aim of the objective function for the Sweet Smell Fertilizer Company should be to value Decision variables: X = number of pounds of compost in each bag Y = number of pounds of sewage waste in each bag Objective function, in cents 2= x+Y 80 75- 70- 65- 60- 55- 50 45 40- 35- 30- 25- 20- 15 10 5- 0 Subject to: 1X + 1Y V 50 (C1) 1X + OY V 30 (C2) 35 40 45 50 55 60 65 70 75 80 V40 (C3) OX + 1Y X Y Z 0 Subject to: 1X + 1Y 50 1X + OY 30 (C1) (C2) (C3) 40 OX + 1Y X,Y 20 On the graph on right, constraints C1, C2 and Cz have been plotted using the line plotting tool. Using the point drawing tool, plot all the corner points for the feasible area. The optimum solution is: X=(round your response to the nearest whole number). Y = (round your response to the nearest whole number). Optimal solution value Z (in cents) = (round your response to the nearest whole number).
