Department A Department B Overhead costs (expected) Normal activity (machine hours) $120,000 16,500 $47,000 1,800 Required: 1. Compute a predetermined overhead rate for the plant as a whole based on machine hours. Round your answer to two decimal places. 9.13 per machine hour $ 2. Compute predetermined overhead rates for each department using machine hours. (Note: Round to two decimal places, if necessary.) Department A 7.27 per machine hour Department B $ 26.11 per machine hour 3. Conceptual Connection: Job 73 used 20 machine hours from Department A and 50 machine hours from Department B. Job 74 used 50 machine hours from Department A and 20 machine hours from Department B. Compute the overhead cost assigned to each job using the plantwide rate computed in Requirement 1. Repeat the computation using the departmental rates found in Requirement 2. Round final answers to the nearest cent, if necessary. Job 74 Plantwide Departmental $ Job 73 639.10 $ 639.10 509 1,827.70 Which of the two approaches gives the fairer assignment? Departmental rates
