Reconsider the Wyndor Glass Co. case study introduced in Section 2.1/ in class. Suppose that the estimates of the unit profits for the two new products now have been revised to $500 for the doors and $350 for the windows. (The number of the products are required to be integer.)

a. Formulate this same model algebraically. (Please clearly define all the decision variables, clearly write down the objective function and each constraints) b. Formulate and solve the revised linear programming model for this problem on a spreadsheet.
