	To
From	A		B		C		Supply
X	$10		$19		$12		150
Y	$17		$13		$9		100
Z	$20		$18		$14		50
Demand	80		120		60

Part 2

Based on the given demand and supply, the given transportation problem is:

unbalanced

balanced

Before finding the initial solution, a dummy

(blank) should be introduced.

The northwest-corner cell for the given transportation matrix is

Y TO A

Z TO A

X TO A

Part 1:

A) The starting solution using northwest-corner method is:

(Note: You must enter a shipment in every cell, even if the shipment is 0.)

Part 2
