Answer:Break-even point (units)= 4,090units  , Â
a. Product Q -2,045 units
b. Product Z -2,045 units
Explanation:
Given
Product Selling Price Variable Cost per Unit Contribution Margin per Unit Q Â Â Â Â Â Â Â Â Â $320 Â Â Â Â Â Â Â Â Â Â Â $150 Â Â Â Â Â Â Â Â Â Â Â Â Â Â $170
Z Â Â Â Â Â Â Â Â Â Â 220 Â Â Â Â Â Â Â Â Â Â Â Â Â 180 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 40
Using the formulae
Break-even point (units)= Total fixed costs / Weighted average contribution margin
But weighted Q contribution: $170 x 50% Â = $ 85
weighted Z contribution: Â Â $ 40 x 50% Â = $ Â 20
Total Mix contribution(Weighted average contribution margin)=$105
Break-even point (units)= $429,450/ $105
Break-even point (units)= 4,090units
Now, for each product:
Q= 4,090units x 50%= 2,045 units Â
Z= 4,090units x 50%= 2,045 units
Therefore,
a. Product Q -2,045 units
b. Product Z -2,045 units
