EXERCISE 6-17 (30 MINUTES)

1. The CM ratio is 30%.

Total Per Unit Percent of Sales

Sales (19,500 units)... $585,000 $30.00 100%

Less variable expenses ... 409,500 21.00 70

Contribution margin... $175,500 $ 9.00 30%

The break-even point is:

Sales = Variable expenses + Fixed expenses + Profits

$30.00Q = $21.00Q + $180,000 + $0

$9.00Q = $180,000

Q = $180,000 ÷ $9.00 per unit

Q = 20,000 units
