Answer:
a.
Break even in units of QQ is 7930 units
b.
Break even in units of ZZ is 1400 units
Explanation:
To calculate the break even in units of each product, we first need to find out the overall break even point in units for the company. The over all break even point in units for a two product company is,
Overall Break even in units = Total Fixed costs / Weighted average contribution margin per unit
Where,
Weighted average contribution margin per unit = Weight of Product A in sales mix * Contribution per unit of Product A + Weight of Product B in sales mix * Contribution per unit of Product B
Weighted average CM per unit = 0.85 * 260 + 0.15 * 180
Weighted average CM per unit = $248 per unit
Over all break even in units = 2313840 / 248 = 9330 units
a.
Break even in units Product QQ = 9330 * 0.85 = 7930.5 rounded off to 7930 units
b.
Break even in units Product ZZ = 9330 * 0.15 = 1399.5 rounded off to 1400 units
