Answer:
Variable cost per unit= $4
Step-by-step explanation:
Giving the following information:
We have determined that the highest and lowest bills were $5,600 and $3,200 for January and September. We produced 1,200 and 600 units in these months.
To calculate the variable cost per unit, we need to use the high-low method. We will use the following formula:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (5,600 - 3,200) / (1,200 - 600)
Variable cost per unit= $4
