Answer:
(A) 5,455 units
(B) 4,667 units
Explanation:
In this question we use the formula of break-even point in unit sales which is shown below:
= (Fixed cost) ÷ (Contribution margin per unit)
where,
Contribution margin per unit = Selling price per unit - Variable expense per unit
(A) For Vendor B
The Break-even point in units = ($60,000) ÷ ($24 - $13)
= ($60,000) ÷ ($11)
= 5,455 units
(B) For Vendor B
The Break even point in units = ($70,000) ÷ ($24 - $9)
= ($70,000) ÷ ($15)
= 4,667 units
