A company develops the following Linear Programming problem to minimize the cost of producing two types of steel pins commonly used the construction industry. The objective function is the profit for the company (in dollars per production batch). The company would like to maximize the profit in solving this problem. Objective:Maximize Z= 60X1 + 50 X2 Subject to:X2 + X1 <= 220 0.1 X1-0.12 X2 >= 0 X1 - X2 <= 120 X1, X2 >= 0 (non-negativity conditions) For each task below, use screen captures of your setup using Excel Solver. Show the formulas of the cells to make out task simpler in grading. Task 1:Solve the problem graphically. State the solution found for the two decision variables. State the value of the objective function for the optimal solution found. In the graphical solution, label the corner points. Task 2:Solve the problem using Excel Solver. State the exact solution found by Excel for the two decision variables. State the value of the objective function for the optimal solution found. Task 3:Since the number of pins to be produced needs to be an integer solution, solve the problem with Excel to obtain an integer solution. State the value of the objective function for the optimal solution found.
