Question

Consider the following linear programming problem. Maximize p = 7x + 5y + 6z subject to the constraints

 x + y − z ≤ 12
 x + 2y + z ≤ 32
 x + y ≤ 20
 x ≥ 0 , y ≥ 0 , z ≥ 0 .

  1. (a)  Write down the initial tableau for this problem.

  2. (b)  Perform a single iteration of the Simplex Method and identify the solution to the resulting tableau. Is it optimal? If not, identify the next pivot. If so, report the objective value.
