an appliance company has a warehouse and two terminals. to minimize shipping costs, the manager must decide how many appliances should be shipped to each terminal. there is a total supply of 1200 units in the warehouse and a demand for 400 units in terminal a and 500 units in terminal b. it costs $12 to ship each unit to terminal a and $16 to ship to terminal b. how many units should be shipped to each terminal in order to minimize cost?
If there are x units shipped to trm A
and y shipped to trm B, then you want to minimize
c = 12x+16y
now graph the constraints and evaluate c at each vertex of the region.
