EXERCISE 6-7 (10 MINUTES)

1. To compute the margin of safety, we must first compute the break-even

unit sales.

Sales = Variable expenses + Fixed expenses + Profits

$30Q = $20Q + $7,500 + $0

$10Q = $7,500

Q = $7,500 ÷ $10 per unit

Q = 750 units

Sales (at the budgeted volume of 1,000 units) .... $30,000

Break-even sales (at 750 units) ... 22,500

Margin of safety (in dollars) ... $ 7,500
