10. Suppose you solved a linear programming problem to decide how many of three different types of products to make in order to maximize profits subject to a constraint on machine time available. Suppose the machine time constraint had a shadow price of 0. What does this mean? What does this tell you about the slack in the constraint? Why? For the same problem, suppose the reduced cost for one of the products was 2. What does this mean? What does this tell you about how many of that product should be made in the optimal solution and why
