  2. The maximal profit occurs at the feasible point (0, 30) and has value equal to 90. The values of at the other corner points are 0, 65, and 50.
    1. Applying the Northwest Corner Rule gives rise to the feasible solution shown here.

      The cost of this solution is 65. The indicator value for the cell (II, 1) is −7, and the indicator value for the cell (II, 2) is −4.

    2. Consequently, this solution is not as cheap as possible. Using two iterations of the stepping stone method, we reach the following tableau, which is optimal (cost of 43).
