Bratton, Golubeva and Ghosh is a small law firm that employs $10$ partners and $12$ support persons. The firm uses a job$-$order costing system to accumulate costs chargeable to each client, and it is organized into two departments, the Research and Documents Department and the Litigation Department. The firm uses predetermined overhead rates to charge the costs of these departments to its clients. At the beginning of the year, the firm$$s management made the following estimates for the year:

Department

Research and Documents Litigation

Research$-$hours $24,000---$

Direct attorney$-$hours $9,00018,000$

Direct attorney cost $$450,000$ $$900,000$

Departmental overhead cost $$840,000$ $$360,000$

The predetermined overhead rate in the Research and Documents Department is based on research$-$hours, and the rate in the Litigation Department is based on direct attorney cost.
