,Answer: a. 9,450 units
Step-by-step explanation:
You need to find the weighted average contribution margin for both products.
Product A
Weighted average contribution margin = Contribution margin * Units sold / Total units sold
= 34 * 7,600 / (7,600 + 2,400)
= $25.84
Product B
= 59 * 2,400 / 10,000
= $14.16
Breakeven point in units = Fixed costs/ (Weighted average contribution margin of both A and B)
= 378,000 / (25.84 + 14.16)
= 9,450 units
