Given the following information set up the problem in a transportation table and solvc ior the minimum-cost plan: Suppose the inventory carrying cost has just increased and is now $2 per unit per period. Compute the total cost for the original transportation model with $1 inventory carrying cost, and the new total cost at $2 carrying cost. What is the additional cost for the optimal plan?
