Use the Graphical Technique to Find the Optimal Solution for This

Essay

Use the graphical technique to find the optimal solution for this objective function and associated constraints.
Maximize: Z = 8A + 5B
Subject To:
Constraint 1 4A + 5B ≤ 80
Constraint 2 7A + 4B ≤ 120
A, B ≥ 0
Graph the problem fully in the following space. Label the axes carefully, plot the constraints, shade the feasibility region, identify all candidate corner points, and indicate which one yields the optimal answer.
