VlaKe vs. buy (our company makes a variety of products. A large order for three products has just been received from a customer who also requested a very short due date. A quick calculation revealed that the limiting 'esource is the labor time; only 200 labor hours are available, and that is not enough to make all the 'equested units of products. Some units must be outsourced to subcontractors. iwo subcontractors are available. Subcontractor A has low prices, but can only provide a maximum of 50 units of all products in total. Sub-contractor B is more expensive, but can provide any number of units 3f any product. (our company wants to decide how many units of each product to make and how many units to buy irom each subcontractor in order to minimize the total cost. The table below summarizes all necessary nformation. Product 1 Product 2 Product 3 Zost of making a unit lost of buying a unit from Subcontractor A 1. Write on paper an LP model for this problem. (Make sure your LP model includes: definitions of decision variables, an objective, constraints, and bounds on variables.) 2. Implement your model on a computer and determine the optimal solution. 3. Is the feasible region of this problem unbounded
