Answer:
3,600 kilograms
Step-by-step explanation:
Break even = Total fixed cost / Contribution margin per kg. 
 
Total fixed cost = Plant depreciation + Other plant costs + Corporate salaries + Advertising 
 
= €8,000 + €15,000 + €10,000 + €3,000 
 
= €36,000 
 
Sales commission = Selling price * 5% 
 
= €20 * 5% 
 
= €1 per kg 
Variable cost per kg = Direct materials + Direct labor + Variable factory overhead + Sales commission 
 
= €4 + €2 + €3 + €1 
 
= €10 per kg 
 Contribution margin per kg = Selling price - Variable cost per kg 
 
= €20 - €10 
 
= €10 per kg
Break even = Total fixed cost / Contribution margin per kg. 
 
= €36,000 / €10 
 
= 3,600 kilograms
