Question $37(3$ points$)$

You are the production manager for a gear manufacturer. The following report presents the result of a linear program to determine the optimal product mix between four possible products $($Gears A$,$ B$,$ C$,$ and D$),$ which would use the following resources: drilling hours, milling hours, lathe hours, and inspection hours. The coefficients of the objective function represent the profit to be made from the manufacture of each type of gear.
