          Graphical solutions of transportation problems
          Teaching steps

             1.  Guide  students  through  discussion  to  find  solutions  of
                 transportation problems graphically. Remind them that graphs
                 of transportation problems are drawn similar to the way of
                 solving linear programming problems.
             2.  Assist students through discussion to identify  the feasible
                 region and the corner points after the graph is drawn. Lead
                 them to use the corner points to obtain the optimal solution of
                 the given transportation problem.

             3.  Use Examples 7.3 and 7.4 in the Student’s Book to guide
                 students  to  formulate  transportation  problems.  Encourage
                 students to explore additional resources, such as online
                 tutorials,  or reference  books, to  deepen  their  understanding
                 and further practice.
             4.  Require students to attempt Exercise 7.2 in the Student’s Book.
                 Advise them to submit their work. Check the correctness of
                 their answers, and provide them constructive feedback.
