"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:
Component Machine
Shaper Grinder
1 6 4
2 4 5
3 4 2
The shaper is available for 120 hours, and the grinder is available for 110 hours. No more than 200 units of component3 can be sold, but up to 1000 units of each of the other components can be sold. In fact, the company already has orders for 600 units of component1 that must be satisfied. The profit contributions for components 1, 2 and 3 are $8, $6, and $9 respectively.
