Answer and Explanation:
The computation is shown below:
As we know that
Break even point = (Fixed cost) ÷ (Contribution margin per unit)
where,
Contribution margin per unit = Selling price per unit - Variable expense per unit
a. The break even point in sales units is
= ($71,424) ÷ ($51 - $27)
= ($71,424) ÷ ($24)
= 2,976 units
b. In case when the sale price increased to $58 per unit, the break even point is
= ($71,424) ÷ ($58 - $27)
= ($71,424) ÷ ($31)
= 2,304 units
