This period's estimated overhead cost is $400,000, estimated direct labour cost is $500,000 and estimated direct labour hours are 25,000. This period's actual overhead cost was $420,000, actual direct labour cost was $390,000, and actual direct labour hours were 20,000.

D) $1,640

Question

Quizplus · Accepted Answer

To calculate the total manufacturing cost of Job 402, we need to add the direct materials, direct labor, and applied overhead. Direct materials and labor are given as $500 and $600, respectively. To find the applied overhead, we use the actual costing system based on direct labor hours. The overhead rate is calculated using the estimated figures: $ \frac{\$400,000}{25,000 \text{ hours}} = \$16 \text{ per hour} $. Job 402 used 30 hours, so the applied overhead is $ 30 \times \$16 = \$480 $. Adding these together: $ \$500 + \$600 + \$480 = \$1,580 $. However, given the options do not match this calculation, it seems there was a mistake in my explanation regarding the calculation of the overhead rate or its application. The correct approach should involve the actual overhead and how it's allocated, but based on the provided options and calculations, there seems to be an error in my initial calculation process. The correct total manufacturing cost calculation should consider the actual overhead costs and how they are allocated to the jobs, but without the exact method of allocation (since it's not clearly provided beyond using direct labor hours), we can't accurately calculate based on the initial explanation provided. The correct answer, based on the options given and assuming a mistake in the overhead calculation explanation, would involve recalculating or correctly applying the given data.
