Use the graphical solution of Maggie’s dessert problem to determine all values of the right-hand side of the total daily gram requirement that make the model infeasible—that is, it has no feasible solutions.

Modify Monet’s product mix model so that there is no maximum sales constraint. (In the Solver dialog box, highlight the constraint and click on the Delete button.) Does this make the problem unbounded? Does it change the optimal solution at all? Explain its effect.
