The Dreskin Development Company is building two apartment complexes. It must decide how many units to construct in each complex subject to labor and material constraints. The profit generated for each apartment in the first complex is estimated at $900, for each apartment in the second complex, $1,500. A partial initial simplex tableau for Dreskin is given in the following table:
Cj $900 $1500 $0 $0
Solution Mix X1 X2 S1 S2 Quantity
14 4 1 0 3360
10 12 0 1 9600
