Mаngо Skаtes hаs оutlet stоres in Gilroy and Newark. Their A-Line model is produced at factories in Akron and Birmingham. The cost of shipping a pair of A-Line skates from Akron to Gilroy is $9; from Akron to Newark, $8; from Birmingham to Gilroy is $7; and from Birmingham to Newark, $5. Suppose that the Gilroy outlet needs at least 120 pairs and the Newark store needs at least 90 pairs. The factory in Akron can produce no more that 100 pairs in time for shipping, and the factory in Birmingham can produce no more than 150 pairs in time for shipping. Setup the linear programming model to minimize cost. Solve by the dual method! Enter the numbers in the spaces below. There is not enough time for you to have a reasonable chance of creating the dual and solving it, so I will help a little. Below is the dual problem and the associated simplex tableau. Solve the dual but remember where the answers to the original problem are located when you finish.
