Is the resulting Transportation Matrix "Optimal" ? * 4 points No, since there are still reduced costs 0. Yes, since all reduced costs are > 0. Yes, since all reduced costs are A company distributes its products from four source to four retails stores. The supply capacities of the sources SI, S2, S3, & $4, are respectively 37, 51, 45, & 37. Whereas the demand at each of the four retail R1, R2, R3, & R4 stores are respectively 43, 43, 40, & 44. The below table summarizes the costs of transportation from source S; to destination Ri.
