Question: 2 THE FOLLOWING QUESTIONS WILL BE ANSWERED BY TAKING INTO CONSIDERATION THE TABLE VALUES GIVEN. THE CHANGE ASKED IN EACH COMPLAINT WILL NOT BE PUT IN THE SOLUTION OBTAINED BY WRITING IN UNGO. THE SOFTWARE WILL NEVER BE USED a) According to the Lindo screen output above; What is the value of the variables X 1, X 2, X 3, Xa and the purpose function? b) Is there an increased constraint (resource)? If so, which or how much of which has it increased? c) 3. If we make the constraint x 4 2 55 instead of X 42 50, does the value of the purpose functionchange? What happens to the new value if it changes? Explain. d) If we add the constraint X2 = 2 to the model , does the value of the purpose function change? Explain. e) If we take into account the X 3+X4=80 constraint (2nd constraint), how much can we increase the profit at most without disturbing the optimal solution set ?
