Answer:
a. Sales volume = (Fixed costs + Target income) / Contribution margin per unit
Fixed costs = ( Percentage of fixed Selling and Admin expenses) +
Percentage of fixed Manufacturing expenses
= 600,000 * 80% + 720,000 * 75%
= 480,000 + 540,000
= $1,020,000
30,000 units = (1,020,000 + 900,000) / Contribution Margin per unit
Contribution margin per unit = 1,920,000/30,000
= $64
Sales per unit = Contribution margin per unit + Variable cost per unit
Variable Cost per unit = 21 + 10 + (24*25%) + (20 * 20%)
= $41
Sales per unit = 64 + 41
= $105 per unit
b - 1. Fixed costs = ( Percentage of fixed Selling and Admin expenses) + Percentage of fixed Manufacturing expenses
= 600,000 * 80% + 720,000 * 75%
= 480,000 + 540,000
= $1,020,000
b - 2. Variable Cost per unit
= Direct materials + Direct Labor + variable percentage of Manufacturing overhead cost per unit + variable percentage of Selling and administrative per unit
= 21 + 10 + (24*25%) + (20 * 20%)
= $41
b - 3. Contribution margin = Selling price - Variable cost
= 121 - 41
= $80
b - 4. Breakeven Point = Fixed Cost / Contribution margin
= 1,020,000/80
= 12,750 units
