Find an initial solution to the following transportation problem. To B From A C Y Z Demand $10 $17 $20 80 $19 $13 $18 120 $12 $9 $14 70 Supply 100 150 50 Based on the given demand and supply, the given transportation problem is unbalanced Before finding the initial solution, a dummy destination should be introduced. The starting solution using northwest-corner method is: From Supply (Note: You must enter a shipment in every cell, even if the shipment is 0.)
