However. Mr$.$ Jensen now has learned that, in eddition to the limited number of labor hours available, two ocher factors will limit the production levels that can be actiered this November. One is that the company's vendor for power supply units will only be able to pro $10,000$ of these units for November $(2,000$ more than his usual monthly shipment$).$ Each power saw and each power drill requires cne of units. Second, the vendor who supplies a key part for the gear assemblies will only be able to provide $15,000$ for November $(4,000$ mor for other months$).$ Each power saw requires two of these parts and each porter drill requires one.
