LO 3, 4, 6 Maxs.t.1A+3B902A+3B5A+5B400A+1B10Constraint3Constraint1Constraint2 Figure 2.22 shows a graph of the constraint lines. a. Place a number ( 1.2, or 3 ) next to each constraint line to identify which constraint it represents. b. Shade in the feasible region on the graph. Figure 2.22 Graph of the Constraint Lines for Exercise 21 Problems c. Identify the optimal extreme point. What is the optimal solution? d. Which constraints are binding? Explain. e. How much slack or surplus is associated with the nonbinding constraint
