Modify the original Grand Prix example as follows.

Increase the demands at the regions by 200 each, so that total demand is well above total plant capacity.

However, now interpret these “demands” as “maximum sales,” the most each region can accommodate, and change the “demand” constraints to become “”

constraints, not “
” constraints. How does the optimal solution change? Does it make realistic sense? If not, how might you change the model to obtain a realistic solution?
