Graph is not necessary because I've already done that part, but I do not know how to get the extreme points or calculate the optimal solution.

(5.5 points) 6.Using the graphical method to solve the following linear programming. Maximize Profit = ($50.X) + ($30.X) Subject to (40X) + (20 * X,) s 3200 (80X ) +(100 X,) s 8000 Xi 20, X220 X, 560 (2 pts) Graph each constraint and identify the solution feasible region. pts) Identify the extreme solutions. (1.5pt) Calculate the optimal solution
