2. A company man ufactu ring fine glass accessories produces color glass vases with a flower pattem. Each vase is produced from liquid glass by an artist glass-blower and then set in a storage room to cool to the room temperature. The vases are made in two sizes-large and smal-but since the production processes are nearly identical, the two types of vases share the same resources. Each vase, irrespective of its size, takes 20 minutes of the artist's work. The artist works 40 hours each week. A small and a large vase require 10 az. and 20 oz of colored glass, respectively. A total of 1,600 oz. of colored glass is available per week. In addition, a small glass oCcupies 2 units of storage space, whereas a large vase occupies 3 units of storage space. The total available storage is 260 units. A small vase contributes $10 to earnings and a large vase contributes $12 to earnings. The company would like to maximize its con tri bution to earnings. Write the objective function of this problem according to the parameters above in terms of two decision variables S (small) and L (large). a (0.5 point) b. Write each of the constraint functions. (0.5 point each) Graph the optimization model: plot and label each constraints and shade the feasible region. (4 points) C. d. Solve for the optimal product mix. What values of the decision variab les retum the maximum contribution to earnings? What is the maximum contribution to earnings? (4 points)
