A production process consists of two stages with one worker at each stage. Stage (assembly) is automated and has a processing time of 5 minutes per unit. The output of Stage 1 is then inspected and repaired, if necessary, at Stage 2 (inspection and repair). Every unit is inspected. However, there is only a 20% probability that repair is needed. The inspection time is 1 minute per unit while the repair time is 25 minutes per unit. What is the output capacity of the process?
