Answer:
$8,000 shirts
Step-by-step explanation:
The formula to compute the break even quantity is shown below:
= (Fixed expenses ) ÷ (Contribution margin per unit)
where,
Fixed expenses = Administrative cost + sales and marketing expenses
= $60,000 + $20,000
= $80,000
Contribution margin per unit = Selling price per unit - Variable expense per unit
= $25 - $5 - $10
= $10
So, the break even quantity is
= $80,000 ÷ $10
= $8,000 shirts
