Q3. The company introduces a new Model 3. Plant X, Y, and Z can produce 8000, 3000, and 8000 units of Model 3 respectively every day. The total demand for Model 3 is 249,500 units. The daily capacities of the three plants for three models are as follows (three plants' capacities for Model 1 and Model 2 are the same as those in Q1): # of units produced in a day Model 1 Model 2 | Model 3 Plant X 8,000 4,000 | 8,000 Plant Y 6,000 6,000 3,000 12,000 4,000 8,000 The total demand for Model 1 and Model 2 also stays the same (300,000 units for Model 1 and 172,000 units for Model 2). Same as in Q1, the company's goal is to fill the total demand and keep the operating cost at a minimum. How can you adjust your linear programming formulation in 01 to solve the company's problem in Q3? a. Are the decision variables the same? If not, what is the difference? b. Is the objective function the same? If not, what is the difference? c. Are the constraints the same? If not, what is the difference
