The following LP formulation represents a transportation problem where raw material (in tons) is transported from Supplier i. i={1,2,3} to Plant j.J={1,2,3). The problem is solved and the optimal objective function value is 5200. Using the sensitivity report, what is the optimality range of the cost of transporting 1 ton of the raw material from Supplier 2 to Plant 3?
