C .C)
Sales price per unit $800
Less: Variable cost per unit (470 )
Contribution margin per unit $330

Breakeven sales in units = (Fixed costs + Target profit) / Contribution margin per unit
Breakeven sales in units = ($10,230 + 0 ) / $330 = 31 units

Expected sales - Breakeven sales = Margin of safety in units
60 units - 31 units = 29 units

Margin of safety in units x Sales price per unit = Margin of safety in dollars
29 units x $800 per unit = $23,200
