Answer:
The correct answer is (b) 10,500 units
Step-by-step explanation:
Solution
Recall that,
The weighted contribution average margin per unit is computed below:
Weighted average contribution margin = The Total contribution margin/Total sold units
Thus,
(8,000 * $30 + (2000 * $60)/ 8000 + 2000
which is
$ 360,000/10,000 = $ 36 per unit.
Now,
We calculate for the break even points in unit
Break-even units Fixed costs / Weighted average contribution margin
$378,000./$ 36 = 10, 500 units
Therefore the break even point is 10, 500 units
