Part b please. Thanks

Consider the following simple assembly process: The numbers below each step refer to the time necessary to process one unit of the product at that step. The process is staffed by three operators with one operator assigned to each of the three steps. Assume no set ups are required, processing times are constant, and no Work in Process (WIP) is permitted beyond that actually being worked on at each process step (i.e., there are no buffers between process steps). (a) What is the Capacity of the process? (b) What is the Capacity Utilization of the operator at Step A? (c) Each operator receives regular wages of 12 /hour for the first 8 hours, and overtime wages of 18 /hour for any additional time. The maximum work time permitted per day is 12 hours. A finished unit sells for 14 while its direct material cost is 6 /unit. Does it pay to use overtime under this cost structure (assuming sufficient demand exists)? (d) Would you hire a skilled operator whose wage rate were 25/ hour (regular time), but could perform Step B at a processing time of 4 minutes/unit? (e) Same as (d), but performs Step A at a processing time of 2 minutes/unit
