Red Star Copy Service processes 2,100,000 photocopies per month at its service center. Approximately 50 percent of the photocopies require collating. Collating is currently performed by high school and college students who are paid $9 per hour. Each student collates an average of 5,000 copies per hour. Management is contemplating the lease of an automatic collating machine that has a monthly capacity of 6,000,000 photocopies, with lease and operating costs totaling $1,550, plus $0.05 per 1,000 units collated.

Question

Determine the monthly volume at which the automatic process becomes preferable to the manual process?
