please answer entire question, i need help. thank you!

A punch press takes in coils of sheet metal and can make five different electrical breaker boxes, denoted by B1, B2, B3, B4, and B5. Each box takes exactly 1 minute to produce. To switch the process from one type of box to another takes 4 hours. Hourly demand rate of B1, B2, B3, B4, and B5 are 10.8, 6, 3.6, 2.1, and 1.2, respectively (a) If the demand rate is same as the arrival rate for each box, what is the arrival rate (ro) in boxes (all types combined together) per hour? (b) Using the same r, in part (a), what would utilization be if there were no setups? (That is, no changeover time consideration when switching among different types of boxes.) (c) Suppose the SCV of the press is 0.2 no matter what a batch size is. Consider setups and move batch process batch. What is the average cycle time when the batch sizes are all equal to 1000 (assume ca = 1)?
