Answer:
Results are below.
Explanation:
First, we will calculate the weighted average contribution margin:
Weighted average contribution margin= (weighted average selling price - weighted average unitary variable cost)
Weighted average contribution margin= (0.6*25 + 0.4*36) - (0.6*13 + 20*0.4)
Weighted average contribution margin= $13.6
Now, the break-even point for the whole company:
Break-even point (units)= Total fixed costs / Weighted average contribution margin
Break-even point (units)= 45,000 / 13.6
Break-even point (units)= 3,309
Now, for each product line:
Plain= 0.6*3,309= 1,985
Fancy= 0.4*3,309= 1,324
