1. Consider the transportation problem and its initial solution in the table below. The cell source 3 dimensional is currently empty. What would be the change in the objective if the largest possible amount were shipped using that route leaving all the supply and demand conditions unchanged?

NOTE: if the first (COSTS) table interior cells show units costs, and margin figures show demand requirements supply capacity in units. The second table shows units allocated in the initial solution.

Transportation Costs	Dest 1	Dest 2	Dest 3	Dest 4	SUPPLY
Source 1	12	18	9	11	45
Source 2	19	7	30	15	145
Source 3	8	10	14	16	50
Demand	80	30	70	60	240/240

Shipments	Dest 1	Dest 2	Dest 3	Dest 4	Row Total
Source 1	30	0	70	5	105
Source 2	0	60	0	85	145
Source 3	50	0	0	0	50
Colum total	80	60	70	90	300/300
