Answer: Weighted contribution 0.09375
Step-by-step explanation:
Product sells for $10
Unit variable cost $7
Product account annual sales $25000
Firm total $8000
Contribution margin = sales price - variable cost
Contribution margin = 10 - 7 = 3
Product annual sales = 25000 / 10 = 2500
Weighted contribution = contribution margin * product units sold / total firm sales sold
(3 * 2500) / 80000 = 0.09375
