d. Assume that the company uses departmental predetermined overhead rates with machine-hours as the allocation base in both departments. What is the departmental predetermined overhead rate in the Machining department? (Round your answer to 2 decimal places.)

Bierce Corporation has two manufacturing departments-Machining and Finishing. The company used the following data at the beginning of the year to calculate predetermined overhead rates: Total Machining Finishing 4,000 Estimated total machine-hours (MHs) Estimated total fixed manufacturing overhead cost Estimated variable manufacturing overhead cost per MH 10,000 s 10,200 24,400 34,600 6,900 2.30$ 4 During the most recent month, the company started and completed two jobs-Job B and Job K. There were no beginning inventories. Data concerning those two jobs follow: Job B Job K Direct materials Direct labor cost Machining machine-hours Finishing machine-hours $21,400 8,400 $21,600 8,400 2,700 1,3e0 600 400
