A system is made up of three processes: Process A, Process B, and Process C. The time to process one unit are 2 minutes , 1 minute , and 0.5 minute on Processes A, B, and C, respectively.

There are no setups that need to be performed prior to a run on any of the three processes. If the process batch size is 4,000 units, but the transfer batch size is changed to 1,000, 500, and 100 for Processes A, B, and C, respectively then how long would it take to process all 4,000 units? (record your answer in minutes)

Process batch =4,000 Transfer batch = various sizes \begin{tabular}{|c|r|r|} \hline Process & \multicolumn{1}{|c|}{\begin{tabular}{c} Process \\ batch \end{tabular}} & \begin{tabular}{c} Transfer \\ batch \end{tabular} \\ \hline A & 4,000 & 1,000 \\ \hline B & \begin{tabular}{r} 1000,1000, \\ 1000,1000 \end{tabular} & 500 \\ \hline & 500,500, & \\ & 500,500, & \\ C & 500,500, & \\ & 500,500 & 100 \\ \hline \end{tabular}
