Suppose you are given the following linear programming model to maximize profit from a production plan, where x1 denotes the quantity of product 1 to make, etc. Max23x1+18x2+15x3 (profit) Subject to (Machine) 5x1+4x2+3x3160 minutes (Labor) 4x1+10x2+4x3200 hours (Materials) 2x1+2x2+4x3200 pounds (Product 2 max) x216 units (Non-negativity) x10,x20,x30 i. Are any constraints binding? If so, which ones? ii. If the profit on product 3 were changed to $22 a unit, what would the values of the decision variables be? What would the overall total profit be at the new optimal production plan? iii. If the profit on product 1 were changed to $22 a unit, what would the values of the decision variables be? What would the overall total profit be at the new optimal production plan
