Please finish my question B (forget the number in blank shett)

Consider the following network representation of a transportation problem. The supplies, demands, and transportation costs per unit are shown on the network. (a) Develop a linear programming model for this problem; be sure to define the variables in your model. Let x11= amount shipped from Jefferson City to Des Moines x12= amount shipped from Jefferson City to Kansas City x13= amount shipped from Jefferson City to St. Louis x21= amount shipped from Omaha to Des Moines x22= amount shipped from Omaha to Kansas City x23= amount shipped from Omaha to St. Louis Min 15x11+9x12+8x13+8x21+10x22+26x23 s.t. From Jefferson City x11+x12+x1330 From Omaha To Des Moines To Kansas City To St. Louis Solve the linear program to determine the optimal solution
