In Problems, complete both of the following.

(a) State the given problem in a form from which the simplex matrix can be formed (that is, as a maximization problem with " constraints).

(b) Form the simplex matrix and circle the first pivot entry.

Minimize g = 3x + 8y subject to
                                 4x - 5y ≤ 50
                                    x + y ≤ 80
                                 -x + 2y ≥ 4
                                x ≥ 0, y ≥ 0
