Answer:
Total direct labor cost=$20,000
Explanation:
First, we need to calculate the direct labor cost per unit:
Direct labor cost per unit= total cost / number of units
Direct labor cost per unit= 21,500 / 8,600
Direct labor cost per unit= $2.5
Now, the total cost for 8,000 units:
Total direct labor cost= 2.5*8,000
Total direct labor cost=$20,000
