4. A numerically controlled machining center has an average processing capacity of 5000
units per day. It receives an average of 3000 units of inventory from another machining center
and it has to supply an average of 1000 units of finished goods to the packaging section.
Assuming that the company incurs a significant cost for carrying finished goods supplied to
the packaging section, the flow rate of the machining process is:
