Answer:
Contribution margin per unit = $85 per cubic yard
Contribution margin ratio = 56.67%
Explanation:
The computations are calculated below:
Contribution margin per unit = Selling price per cubic yard - variable cost cubic yard
= $150 - $65
= $85 per cubic yard
Contribution margin ratio would be
= (Contribution margin per cubic yard) ÷ (Selling price per cubic yard) × 100
= ($85) ÷ ($150) × 100
= 56.67%
And, The statement of contribution margin income for the month of August is shown below:
Sales (240 cubic yards × $150) $36,000
Less: Variable cost (240 cubic yards × $65) ($15,600)
Contribution margin $20,400
Less: Fixed expenses per month ($15,000)
Net income $5,400
