The table given below provides the shipping costs and supply available at each source. Find the minimum-cost shipping solution for the transportation problem. Provide a table of shipping quantities and the minimum value for the objective function for the following methods:

* The northwest-corner rule
* The intuitive lowest-cost method

What is the difference in costs for the two methods? Which solution do you believe is better?

If the cost per unit from Source 2 to Destination 2 is increased from $3 per unit to $6 per unit, does the solution change? If so, how?
