Consider the transportation table below. The solution displayed was obtained by performing some iterations of the transportation method on this problem. Source Destination Yuma $8 Miami Denver L Supply Houston $2 $41 St. Louis $5 10 $ 6LS 201 2020 Chicago Demand $ 20 The total cost of the current solution provided = $ . Using stepping stone method, to perform an improvement iteration, the improvement index for the unused cell will be: Houston - Yumam Houston - Miami = 0 St. Louis - Miami = 0 Chicago - Denver DOOD Based on the improvement index for each of the unused cells, in the first improvement iteration, unused cell Houston - Miami should get an assignment of units. The improved transportation flow will be: (Note: You must enter a shipment in every cell, even if the shipment is 0.) From Denver Miami Supply Yuma | $2 $8 $1 Houston St. Louis Chicago The total cost of the improved solution = SU. Enter your answer in each of the answer boxes
