Answer:
$84.40
Explanation:
The Manufacturing overhead is a mixed cost, we need to separate the variable and fixed element first.
Using High - Low Method this will be :
Variable Element = ($ 769,200 - $ 748,500) ÷ 1,000
= $20.70
Total Variable Costs = $53.30 + $10.40 + $20.70
= $84.40
The best estimate of the total variable manufacturing cost per unit is: $84.40
