Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the predetermined overhead rate for each activity:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Machine setups= 27,945/207= $135 per set up
Special processing= 236,500/4,300= $55 per machine hour
Now, we can allocate costs to each product:
Hubs:
Machine setups= 135*115= $15,525
Special processing= 55*4,300= $236,500
Total= $252,025
Sprockets:
Machine setups= 135*92= $12,420
We weren't provided with enough information to calculate the unitary cost. Information regarding direct labor hours and the number of units is missing.
