Answer:
$635,000 and : 34%
Step-by-step explanation:
Margins of safety is the difference between expected sales and the break-even point.
For Zhao, expected sales are 10,000 units
The break-even points in units = fixed cost/ contribution margin per unit
fixed costs = $429,000
Contribution margin per unit = selling price - variable costs per unit
=$187 - $122
=$65
break-even point in units = $429,000/$65
break-even point = 6600 units
Margin of safety = 10,000 - 6600 units
=3400 units
In dollars is equal to margin of safety in units x selling price
=3400 x 187
=$635,000
as a percent of expected sales.
=3400/10000 x 100
=0.34 x 10,000
=34%
