Answer:
Product margin= $9,332
Explanation:
First, we need to allocate the activity cost to product M5:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Processing= 5,945/14,500= $0.41 per machine hour
Supervising= 19,680/800= $24.6 per batch
Product M5:
Processing= 0.41*800= $328
Supervising= 24.6*400= $9,840
Finally, the total cost and the product margin:
Total cost= 32,300 + 42,600 + (328 + 9,840)
Total cost= $85,068
Product margin= 94,400 - 85,068
Product margin= $9,332
