i just needed the answer for the 5th question

5- Suggest a mathematical model for "transportation" to find the minimum cost of transportation.

- Purchase the case study "Apple INC.: Managing A GLOBAL SUPPLY CHAIN" - Read the case study and answer the following questions: Case study questions: 1- Review Apple's Supply Chain for its iPhone product. What differences set it apart from competitors? 2- What are Apple's key advantages in how it manages its supply chain operations? Support your analysis with data from the case. 3- What are the challenges that Apple faces in the future, and what are the implications for its supply chain? 4- As Jessica Grant, What recommendation would you make to the company's vice-president, Phillip Duchene, and why? 5- Suggest a mathematical model for "transportation" to find the minimum cost of transportation. My suggestions: - Start your paper with an Abstract (Analysis) for this case study. - Answer these questions one by one. At first print the question and answer it, again print the question and answer it and then print the question and then answer it. - If you use a table and chart or... do not forget to number. - Do not forget the conclusion. - Do not forget citations if you have any references
