Use Excel to solve the transportation problem as having a minimum cost as depicted on the next slide and then answer the following. 1) What amounts are shipped on each route sldl= s1d2= s2d1 = s2d2= ? 2) What is the minimum cost of these shipments? 3) Give an explanation of the range of optimality of variable s2d1. 4) If any variable has a reduced cost identify the variable and explain what the reduced cost means. 5) Give an explanation of the range of feasibility of s2 and what the shadow price there means. 6) Give an explanation of the range of feasibility of d2 and what the shadow price there means. Please include your Excel file with a least a answer report and sensitivity report when vou conduct vour discussion. Supply Demand $2 di 100 80 $2 s2 120 d2 100 $0.50
