Question 3: 10 POINTS Dolls are manufactured in a two-stage process. The first stage has a processing time of 4 minutes per unit (when producing) and requires a 20-minute setup for each batch. The second stage has a capacity of 15 dolls per hour and has no setup time. What is the capacity of the process (in units per hour) if the batch size is 40? Question 4: 10 POINTS A process is capable of producing 3 units per minute (when producing). After each batch, the process requires a 20-minute setup before production can resume. What batch size (in units) will achieve a target capacity of 60 units per hour?
