1. Describe the difference between support departments and producing departments.
2. Explain five reasons why support cost may be assigned to producing departments.
3. Calculate charging rates, and distinguish between single and dual charging rates.
4. Allocate support center costs to producing departments using the direct method, the sequential method, and the reciprocal method.

Departmental Overhead Rates
The overhead rate for the Grinding Department is computed as follows (assuming the normal level of activity is 71,000 MH):
OH rate = $355,000 71,000 = $5 per MH
The overhead rate for the assembly department is computed as follows (assuming the normal level of activity is 107,500 DLH):
OH rate = $215,000 107,500 = $2 per DLH
