(a)	Suppose that a plantwide cost driver rate is computed by dividing plantwide overhead costs by plantwide practical capacity direct labor hours. Determine the overhead cost applied to job ST101.
(b)	Determine the departmental cost driver rates and overhead costs applied to job ST101 if machine hours are used as the cost driver in the cutting department and direct labor hours are used as the cost driver for the grinding and drilling departments.
(c)	Explain why BravoBravo Steel might prefer a plantwide rate or departmental cost driver rates.
