Answer:
The answer is 51,500 units
Step-by-step explanation:
Break-even sales is a point in which a business or a firm neither make profit nor loss. Total Revenue equals total cost. Break-even sales help to know the point at which business starts to make profit.
Break-even sales is:
Fixed cost/contribution margin.
Where contribution margin is sales price per unit minus variable cost per unit.
In the question, variable cost are decreased by $3.
So the new variable cost is $21 - $3
=$18.
Contribution margin is $24 -$18
$6
Therefore, The break-even sales (units) if the variable costs are decreased by $3 is:
$309,000/$6
=51,500 units
