Can someone please explain in clear steps on how to do this problem? It's overwhelming for me to understand. Thank you!

Allocate overhead using a single plantwide rate, multiple department rates, and activity-based costing Big Sound Inc. manufactures two products: receivers and loudspeakers. The factory overhead incurred is as follows: The activity base associated with the two production departments is direct labor hours. The indirect labor can be assigned to two different activities as follows: The activity-base usage quantities and units produced for the two products follow: 1. Determine a plantwide overhead rate based upon direct labor hours. Direct labor overhead rate: $ X per direct labor hour 2. Determine the total and per-unit factory overhead costs allocated to each product, using the plantwide overhead rate in (1). Round per unit amounts to the nearest whole cent. the production departments, so that the total factory overhead is $420,000 and $294,000 for the Subassembly and Final Assembly departments, respectively. 4. Determine the total and per-unit factory overhead costs allocated to each product, using the multiple production department overhead rate in (3). Round per unit amounts to the nearest whole cent. 5. Determine the activity rates, assuming that the indirect labor is associated with activities rather than with the production departments. Round per unit amounts to the nearest whole cent. Round per unit amounts to the nearest whole cent. 6. Determine the total and per-unit cost assigned to each product under activity-based costing. Round the per unit amounts to the nearest whole cent. multiple production department factory overhead rate method, and activity-based costing
