The sole objective in the above minimum cost problem is to supply the most units (preferably all units) of the demand nodes at minimum cost. How will changing the supply at Node 1 from the current 200 units to 100 units impact the total cost? None of the above. Total cost will decrease, but by an unknown amount. Total cost will not change. Total cost will decrease by a known amount. Total cost will increase, but by an unknown amount. Need more information to answer this question.
