Question 3: Answer the following questions using the sensitivity report of a profit function shown below: a) Report the optimal solution and the optimal value of the objective function. b) Calculate the amounts of slack/surplus and comment on what constraints are binding and which ones are nonbinding c) How much improvement in the objective function will we get if we increase the amount of Aluminum by 8 more units? d) Is it possible to calculate the optimal value of the objective function (according to this sensitivity report) if the coefficient of x changes to 8 and the coefficient of y changes to 7 simultaneously? If it is possible, calculate the optimal value. Show all of the calculations
