help please!!

Find an initial solution to the following transportation problem. The starting solution using northwest-comer method is: INote: You must enter a shipment in every cell, a) The total cost of the intial solution developed using the northwest-corner mothod = $ a) The total cost of the initial solution developed using the northwest-corner method = \$ The starting solution using the intuitive lowest-cost method is: INote: You must enter a shipment in everv cell. even if the shipment is O. b) The total cost of the initial Lolution developed using the intuitive lowest-cost method = $ c) The total cost of the optimal solution =$
