Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Estimated machine-hours= 157,000
Estimated fixed manufacturing overhead= $650,000
Variable manufacturing overhead cost per machine-hour $4.40
First, we need to calculate the predetermined overehad rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= (650,000/157,000) + 4.4
Predetermined manufacturing overhead rate= $8.54 per machine-hour
Job 400:
Direct materials $320
Direct labor cost $230
Machine-hours used 37
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated overhead= 8.54*37= $315.98
Finally, we need to determine the unitary cost for Job 400:
Total cost= 320 + 230 + 315.98= $865.98
Unitary cost= 865.98/50= $17.32
