For the following linear programming problem: Max -2.5X + 4Y s.t. -2X + 3Y 0 (Note: IN ORDER TO GET FULL MARKS, SHOW ALL CALCULATION STEPS. FAILURE TO DO SO WILL RESULT IN A SCORE OF O".) a) Solve the LP Model using the graphical method. Label your graph completely. State your optimal solution and objective function value. b) Calculate the Slack/Surplus for each constraint. c) Calculate the Shadow/dual Prices for each constraint. d) How much would the objective function value be increased or decreased or remain the same If the right-hand side of constraint ] is decreased to 95? The Allowable Increase and the Allowable Decrease of Constraint 1 are 10 and 21.25, respectively. e) Allowable Increase and Allowable Decrease of Constraint 2 are IE+30 and 34, respectively. If the right-hand side of constraint 2 is increased to 75, then how much would the objective function value be increased, decreased, or remain the same? When you completed a question, upload the solution immediately before moving to the next question. If this is your last question then's vomit the test
