For this problem, let's consider a simplified version of the problem similar to the distributor in Brazil. The firm we are considering has three facilities, each with the capacity to serve 20 million units of demand. Assume that there are nine demand regions and that a demand region must be served by only one facility. If the demand (in millions) for the nine regions is 9, 7, 6, 6, 7, 6, 6, 7, and 6, explain why this problem has no feasible solution.
