Using the Northwest Corner transportation method, solve the following approach: A tire manufacturing company has two warehouses (B1 and B2), daily you have to send 800 tires to warehouse 1 and 1000 to warehouse 2. Understanding that each warehouse can be supplied from any of the company's three factories manufacturing (F1, F2 and F3). F1 production capacity is 500 tires daily, the F2 with 900 tires per day and the F3 with 600 tires per day. The variable transportation costs are: F1 a Bl F2 a B1 $70 $90 F3 a B1 $60 F1 a B2 F2 a B2 $50 $60 F3 a B2 $70 It is desired to determine the optimal combination of production and transportation, so that costs are minimized. Make a conclusion about the result obtained, what does it mean?
