Answer:
Product margin= $9,607.5
Step-by-step explanation:
First, we need to calculate the allocation rates:
Assembly= 1,533,840 / 77,000= $19.92 per machine-hour
Processing orders= 91,065 / 1,950= $46.7 per order
Inspection= 139,788 / 1,980= $70.6 per inspection-hour
Now, we need to allocate overhead:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Assembly= 19.92*660= 13,147.2
Processing orders= 46.7*50= 2,335
Inspection= 70.6*10= 706
Total= $16,188.2
Finally, the product margin for product S78N:
Product margin= 430* (124.3 - 51.25 - 13.06) - 16,188.2
Product margin= $9,607.5
