Formulate the Trans-shipment problem as an Integer Linear Program and solve using Solver. Source A can supply 320 units and Source B can supply 350 units. The numbers next to the arcs are the shipping cost / unit. The demand at each node is mentioned as : From the options below, select ALL the correct options. Penalties for incorrect options selected The number of units supplied from 3 to 2 is 150 The number of units supplied from 3 to 5 is 150 No units are supplied from A to 4 The no. of units supplied from B to 1 is less than the no. of units supplied from B to 6 The total cost of shipping is $4900 No units are supplied from A to 2 The total cost of shipping is $3700 The total number of units supplied from 5 to 7 is 90 The total number of units supplied from 2 to 7 is 90 The no. of units supplied from B to 1 is 180
