Formulate the mathematical model - DO NOT attempt to solve. A shop must deliver 300 units of A each month for the next 3 months. There are two different processes. each using labor and Raw Material M. which can he used to make the A's. Input and output for 1 hr of operation of each are: Input Output M (lb) Labor (hr) Units of A Process I 6 3 l2 Process 2 2 4 9 However. Process 2 is unavailable for use in the third and nal month: it can be utilized only during the rst 2 months. Each month the shop has available up to 110 lb of M at $36/lb and up to 95 hr of labor at $26/hr, but unused pounds of M and hours of labor in one month cannot be saved for use in a later month. However, extra units of A made in one month can be stored for later use at a cost of $20/unit-month. The shop pays only for storage, labor. and the raw material labor used. Determine a production schedule which minimizes total costs
