Answer:
$310,000
Step-by-step explanation:
The direct labor cost is equal to the wages of machine operators i.e $310,000 as it is directly related to the production units
Moreover, the selling and admin personnel is a period cost that includes the major part of selling and admin expenses, therefore, it would not be considered
Plus the direct labor cost comes under the product cost like direct material cost, direct labor cost, etc
Hence, the direct labor cost is $310,000
