please help me with this thank you!

Allocate overhead using a single plantwide rate, multiple department rates, and activity-based costing Big Sound Inc. manufactures two products: recelvers 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 quantikies 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. 3. Determine the factory overhead rates under the muliple productoo department rate method. Assume that indirect labor is associated with the production departments, so that the total factery everhead is $420,000 and $294,000 for the Subassembly and Final Assembly departenents, reipectively 4. Determine the total and per-unit factory overhead costs allocated to each product, wing the mutple production department overinesd rates in (3). Round per unit amounts to the nearest whole cent. 5. Determine the activity rates, assuming that the indirect labor is assocated with activities rather than with the production departments. Round per unit amounts to the nearest whole cent. 4. Determine the total and per-unit factory overhead costs allocated to each product, using the multiple production department overhead rates 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. 6. Determine the totat and periunit cost assigned to each product under activity-based costing. Round the per unit amounts to the nearest whole cent. 7. Comment on the differences in the per-unit overhead allocated to each product using the single plantwide factory overhead rate method, the multiple production department factory overhesd rate method, and activity-based costing. The plantw de overhead method allocates 5 X of overhead to each product, while the multiple production department method allocates \$ overtead to receivers and 1 X to loudspeakers. Both the plantwide and multiple production department overhead methods of overhead because they account for how each product consumes overhead. In contrast, activity based costing allocates 1 of fectery overhead to receivers and : x to loudspeakers. Activity-based costing V accuretely allocates factory overhead because for how each product consumes overhead. Loudspeakers have setups than do receivers. In addition, loudspeakers require quality control inspections than do receivers. As a result, loudspeakers have activity costs than receivers
