Find an initial solution to the following transportation problem. The starting solution using northwest-corner method is: a) The total cost of the initial solution developed using the northwest-corner method = $ The starting solution using the intuitive lowest-cost method is: Los Angeles Panama City From Mexico City Detroit Supply 120 $6 $8 $17 $19 70 $20 $24 50 Ottawa Demand 80 100 60 (Note: You must enter a shipment in every cell, even if the shipment is 0.) To From Los Angeles Calgary Panama City Supply $8 $18 Mexico City 120 $13 $19 Detroit 70 $10 $24 Ottawa 50 Demand 80 To Calgary $18 $13 $10 $6 $17 $20 100 60 a) The total cost of the initial solution developed using the northwest-corner method= = $0. The starting solution using the intuitive lowest-cost method is: b) The total cost of the initial solution developed using the intuitive lowest-cost method = $. c) The total cost of the optimal solution = $0.
