If hip is decreased by 1 ton so that fewer tons of p are required to be shipped to destination d then do you expect the total cost of the optimal shipping plan to go up or down? By how much would you expect the cost to change when lad}, is decreased by 1 ton? Give an answer in terms of the optimal dual renes. If you could have an independent contractor deliver some tons of product p to origin 01 then you would effectively reduce the amount of product p that you would have to supply through your own production- What is the greatest delivery charge per ton that you would be willing to pay the contractor? Give an answer in terms of the optimal dual values. If dropAsp {1 cap for some particular origin 0 and product p, then what does the complementary slaekness property tell yell about the optimal solution to the primal LI"?I
