i)
Break-even point in units = Fixed Cost / Contribution Margin Per Unit
Contribution margin per unit = Selling Price per unit - Unit marginal cost per unit or variable cost per unit
| X | Y | Z | Overall Company | |
| Selling Price Per Unit | $8 | $12 | $30 | $50 | 
| Less: Variable cost per unit or unit marginal cost | ($6.50) | ($6.50) | ($14) | ($27.00) | 
| Contribution Margin per unit (a) | $2 | $6 | $16 | $23 | 
| Fixed Cost (b) | $60,000 | |||
| Break-even point in units (b/a) | 2,609 | |||
| Break-even point in dollars ($50 * 2,609 units) | $130,435 | 
ii)
Profit volume ratio or Contribution margin ratio = Contribution Margin per unit / Selling price per unit * 100
| X | Y | Z | Overall Company | |
| Selling Price Per Unit (b) | $8 | $12 | $30 | $50 | 
| Less: Variable cost per unit or unit marginal cost | ($6.50) | ($6.50) | ($14) | ($27.00) | 
| Contribution Margin per unit (a) | $2 | $6 | $16 | $23 | 
| Contribution Margin Ratio (a/b*100) | 19% | 46% | 53% | 46% |

| Desired Profit (b) | $50,000 | $50,000 | $50,000 | $50,000 | 
| Contribution margin per unit (c ) | $2 | $6 | $16 | $23 | 
| Units should be sold to earn a profit of $50,000 (a + b/c) | 55,000 | 18,333 | 6,875 | 4,783 |
