Add cutters to the extruder. Mr. Johnson also considered adding an additional three cutters to the extruder. He knew this would increase the rate at which donuts could be cut and shaped, but he also knew that it would add to the cleaning and setup which had to be performed prior to each step and that it would cost him to purchase and install the new cutters...making this. again, not the ideal option - but a feasible one. In order to make an informed decision, he needs to know this: What is the maximum setup time that could be allowed for each batch if he were to add an additional three cutters without changing the current batch size of eight pounds? Dewey could change his setup time to 13 minutes and still make plenty of donuts to meet the customer demand
