WebbIn solving (2), the shadow prices associated with its constraints are u1 =36, u2 =0, and u3 =6. However, these shadow prices for the constraints of (2) are exactly the optimal values of the decision variables of the ﬁrm’s allocation problem. Hence, in solving the dual (2) by the simplex method, we apparently have solved the primal (1) as well.
