This one question is important, please answer soon.

The following table is a transportation matrix showing the cost ($) per unit of shipping from Plant i to Distributor j. The objective is to minimize shipping costs while meeting the demand placed by each Distributor. There is no shipment between Plant 2 and Distributor 3. Plant 1 Plant 2 Plant 3 Demand Let ij Distributor 1 Distributor 2 10 27 22 14 26 15 410 330 = number units shipped from Plant & to Distributor j a) At optimal solution: I1 = 21 = solve the transportation problem and use the result to fill the boxes below. All answers are equally weighted. 231 = Slack at Plant 1 = #12 = Minimum Cost = $ Slack at Plant 2 = 122 Slack at Plant 3 = 132 = Distributor 3 Supply 28 430 units 18 50 units b) At optimal solution, how much unused capacity is available at each Plant? units 13 = 123 = 320 60 733 =
