Answer:
$40,000
Step-by-step explanation:
For computing the total variable cost, first we have to determine the variable cost per unit which is shown below:
= (Direct materials cost + Indirect materials - variable + Direct labor cost) ÷ (number of units produced and sold)
= ($18,000 + $2,000 + $10,000) ÷ (3,000 units)
= ($30,000) ÷ (3,000 units)
= $10 per unit
Now the total variable cost would be
= $4,000 units × $10 per unit
= $40,000
