1. The contribution margin per unit is calculated as follows:
Total contribution margin (a) .............. $8,000
Total units sold (b) ....... ........ ............ 1,000 units
Contribution margin per unit (a) ÷ (b) . $8.00 per unit

The Foundational 15
The contribution margin per unit ($8) can also be derived by calculating
the selling price per unit of $20 ($20,000 ÷ 1,000 units) and deducting
the variable expense per unit of $12 ($12,000 ÷ 1,000 units).
2. The contribution margin ratio is calculated as follows:
Total contribution margin (a) .............. $8,000
Total sales (b) .............. ........ ............ $20,000
Contribution margin ratio (a) ÷ (b) ...... 40%
3. The variable expense ratio is calculated as follows:
Total variable expenses (a) ................. $12,000
Total sales (b) .............. ........ ............ $20,000
Variable expense ratio (a) ÷ (b) .......... 60%
4. The increase in net operating is calculated as follows:
Contribution margin per unit (a) ..................... $8.00 per unit
Increase in unit sales (b) ............................... 1 unit
Increase in net operating income (a) × (b) ..... $8.00
5. If sales decline to 900 units, the net operating would be computed as
follows:
Total Per Unit
Sales (900 units) .......... $18,000 $20.00
Variable expenses ......... 10,800 12.00
Contribution margin ...... 7,200 $ 8.00
Fixed expenses ............. 6,000
Net operating income .... $ 1,200

6. The new net operating income would be computed as follows:
Total Per Unit
Sales (900 units) .......... $19,800 $22.00
Variable expenses ......... 10,800 12.00
Contribution margin ...... 9,000 $10.00
Fixed expenses ............. 6,000
Net operating income .... $ 3,000
7. The new net operating income would be computed as follows:
Total Per Unit
Sales (1,250 units) ........ $25,000 $20.00
Variable expenses ......... 16,250 13.00
Contribution margin ...... 8,750 $ 7.00
Fixed expenses ............. 7,500
Net operating income .... $ 1,250
8. The equation method yields the break-even point in unit sales, Q, as
follows:
Profit = Unit CM × Q − Fixed expenses
$0 = ($20 − $12) × Q − $6,000
$0 = ($8) × Q − $6,000
$8Q = $6,000
Q = $6,000 ÷ $8
Q = 750 units
9. The equation method yields the dollar sales to break-even as follows:
Profit = CM ratio × Sales − Fixed expenses
$0 = 0.40 × Sales − $6,000
0.40 × Sales = $6,000 Sales
= $6,000 ÷ 0.40
