Find an initial solution to the following transportation problem. Panama City Supply 160 From Mexico City Detroit Ottawa Demand $8 To Calgary $18 $13 $10 80 Los Angeles $6 $17 $20 140 90 $19 $24 100 The starting solution using northwest-corner method is: (Note: You must enter a shioment in every cell, even if the shipment is 0.) From Calgary Panama City | Los Angeles $61 $18 Supply 160 Mexico City $131 $19) Detroit 90 $20 $10 $24 Ottawa Demand 140 a) The total cost of the initial solution developed using the northwest-corner method = $ The starting solution using the intuitive lowest-cost method is: a) The total cost of the initial solution developed using the northwest-corner method = $ 1. The starting solution using the intuitive lowest-cost method is: (Note: You must enter a shioment in every cell, even if the shioment is 0.) From Los Angeles Calgary Panama City Supply $81 Mexico City 160 $17 $19 Detroit 90 $20 L $24 Ottawa 70 Demand 140 80 b) The total cost of the initial solution developed using the intuitive lowest-cost method = $ - c) The total cost of the optimal solution = 57
