If we wish to add the constraint that no more than two of these variables must be positive, how would this be written? X + Y + Z <= 2 1 1 point 2 An integer programming (maximization) problem was first solved as a linear programming problem, and the objective function value (profit) was $253.67. The two decision variables (X, Y) in the problem had values of X = 12.45 and Y = 32.75. Which of the following must be true for the optimal integer solution to this problem? 1 1 point A) X = 12 Y = 32 B) X = 12 Y = 33 C) X = 12 D) Y = 32 E) None of the above 3 Graphically solve the LP Relaxation of the Integer Program problem listed above. What is the Optimal Solution? X 1 = 5.5 X 2 = 3.5 1 1 point 4 Graphically solve the Pure Integer Program problem listed above. What is the Optimal Solution? X
