Assume Business Solutions allocates overhead cost using a plantwide rate based on 4,800 machine hours. Compute total product cost of Job 615. 3. Assume Business Solutions uses activity-based costing. (a) Compute overhead activity rates. (b) Allocate overhead cost to Job 615. (c) Compute total product cost of Job 615 Assume Business Solutions allocates overhead cost using a plantwide rate based on 4,800 machine hours. Compute total product cost of Job 615.
