Answer:
a. 1,500
Step-by-step explanation:
The formula to compute the break even point for earning target profit is shown below:
= (Fixed cost + target profit) ÷ (Contribution margin per unit)
where,
Contribution margin per unit = Selling price per unit - Variable expense per unit
So, the break even point would be
= ($100,000 + $20,000) ÷ ($100 - $20)
= $120,000 ÷ $80
= 1,500 rooms
