A cоmpаny uses а twо-step prоcess to mаke a part. The first step involves a drill press that requires a 60-minute setup time before the production of each batch can begin. After that, one unit can be drilled every 6 minutes. The second step involves attaching the drilled item to another device which takes 8 minutes per unit. Assuming demand is unlimited, what is the ideal batch size of the parts?
