Answer:
$132.70
Explanation:
The computation of the total variable manufacturing cost per unit is shown below
But before that manufacturing overhead per unit is recorded
Variable manufacturing overhead
= (Cost at the highest activity - Cost at the lowest activity) ÷ (Highest activity-Lowest activity)
= [(2000 × 86.90) - (4000 × 55.30)] ÷ (2000 - 4000)
= (173,800 - 221,200) ÷ (-2000)
= 23.70 per unit
Now Total manufacturing cost per unit
= Direct Materials + Direct Labor + Variable Manufacturing Overhead
= $88.40 + $20.60 + $23.70
= $132.70
