The table below summarizes factory availabilities, projected store demands, and unit shipping costs.

a. Derive an initial solution using:

i. Minimum cell cost method

ii. Vogel's approximation method (VAM)

b. Draw a well annotated source-destination chart to illustrate this LP problem

c. Using systematic nomenclature for the variables, write out an LP formulation for the problem in preparation for applying a computer software like 'solver'.
