Answer:
$1.8 per unit
Explanation:
The computation of the variable cost per hour by using high low method is shown below:
Variable cost per unit = (High total cost - low total cost) ÷ (High units produced - low units produced)
= ($80,609 - $37,769) ÷ (43,280 units - 19,480 units)
= $42,840 ÷ 23,800 units
= $1.8 per unit
By applying the above formula we can find out the variable cost per unit
