Vollmer Manufacturing makes three components for sale to
refrigeration companies. The components are processed on two
machines: a shaper and a grinder. The times (in minutes) required
on each machine are as follows:
Machine |

The shaper is available for 120 hours, and the grinder for 110
hours. No more than 200 units of component 3 can be sold, but up to
1,000 units of each of the other components can be sold. In fact,
the company already has orders for 600 units of component 1 that
must be satisfied. The profit contributions for components 1, 2,
and 3 are $8, $6, and $9, respectively.
