Answer and Explanation:
The computation of the variable cost per unit and the total fixed cost is shown below;
a. The variable cost per unit is
= (Highest total cost - lowest total cost) ÷ (Highest units produced - lowest units produced)
= ($440,000 - $300,000) ÷ (5,500 - 2,700)
= $140,000 ÷ 2,800
= $50
b. The total fixed cost is
= $440,000 - 5,500 × $50
= $440,000 - $275,000
= $165,000
