Divisions A and B have estimated manufacturing overhead costs of $170,000 and $340,000, respectively. Division A uses machine hours as the allocation base, and Division B uses direct labor hours as the allocation base. The total estimated machine hours were 36,000, and direct labor hours were 23,000 for the year. Calculate the departmental predetermined overhead allocation rates.
