Answer:
Direct materials cost of $45,000 was incurred in producing the inventory.
Explanation:
Finished Goods Inventory value include the direct material cost dirrect labor cost and manufacturing overhead cost.
As given overhead are applied using rate of 120% of total direct labor cost.
Direct Labor cost = Total overhead applied / Overhead Rate
Direct Labor cost = $78000 / 120% = $65,000
As we know
Finished goods inventory = direct materials cost + direct labor cost + overhead applied
$188,000 = direct materials cost + $65,000 + $78,000
$188,000 = direct materials cost + $143,000
direct materials cost = $188,000 - $143,000 = $45,000
