Description
(a) Define the decision variables and write the linear programming model for the problem in the space provided below  
product 1= x1  product 2= x2  
Assembly Line 1:  10*x1+14*x2<=100  
Assembly Line 2:  7*x1+3*x2<=42  
Maximise:  6*x1+4*x2  
(b) Sketch the feasible region. Give your answer in the worksheet named P1Graph  
(i) You can use QM for Windows to get the graph, copy and paste it onto the worksheet named P1Graph OR  
(ii) You can sketch the feasible region on paper, scan and save it in your computer.  
Copy the image (i.e. graph) and paste it onto the worksheet named P1Graph  
(c’) Write all the vertices of the feasible region and identify the optimal vertex  
What is the optimal objective function value?
