Answer:
a. $48
b. $155,520
Step-by-step explanation:
The computation of the fixed cost and the variable cost per hour by using high low method is shown below:
Variable cost per unit = (High total cost - low total cost) ÷ (High production - low production)
= ($322,560 - $207,360) ÷ (3,480 units - 1,080 units)
= $115,200 ÷ 2,400 units
= $48
Now the fixed cost equal to
= High total cost - (High production × Variable cost per unit)
= $322,560 - (3,480 units × $48)
= $322,560 - $167,040
= $155,520
We simply applied the above formulas
