Chapter 2-An Introduction to Linear Programming & Graphical method1. Consider the following linear programming problemMax8X + 7Ys.t.15X + 5Y ? 7510X + 6Y ? 60X + Y ? 8X , Y ? 0a.Use a graph to show each constraint and the feasible region.b.Identify the optimal solution point on your graph. What are the values of X and Y at the optimal solution?c.What is the optimal value of the objective function?2. For the following linear programming problem, determine the optimal solution by the graphical solution methodMax?X + 2Ys.t. 6X ? 2Y ? 3?2X + 3Y ? 6 X + Y ? 3 X , Y ? 03. Use this graph to answer the questions.Max20X + 10Ys.t.12X + 15Y ? 18015X + 10Y ? 1503X ? 8Y ? 0X , Y ? 0a.Which area (I, II, III, IV, or V) forms the feasible region?b.Which point (A, B, C, D, or E) is optimal?c.Which constraints are binding?d.Which slack variables are zero?4.
