Answer:
Selling price= $210.24
Explanation:
First, we need to calculate the predetermined overhead rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= (488,000 / 61,000) + 2.8
Predetermined manufacturing overhead rate= $10.8 per machine hour
Now, we can allocate overhead to Job X455, and the total cost:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 10.8*80= $864
Total cost= 880 + 1,760 + 864
Total cost= $3,504
Finally, the unitary cost and selling price:
Unitary cost= 3,504 / 20= $175.2
Selling price= 175.2*1.2= $210.24
