Final answer:
The weighted-average contribution margin ratio is 37%.
Step-by-step explanation:
To find the weighted-average contribution margin ratio, we need to multiply each division's contribution margin ratio by its sales mix, and then add them together.
For the Sporting Goods division:
Contribution margin ratio = 30%
Sales mix = 65%
Weighted contribution margin ratio for Sporting Goods = 30% * 65% = 19.5%
For the Sports Gear division:
Contribution margin ratio = 50%
Sales mix = 35%
Weighted contribution margin ratio for Sports Gear = 50% * 35% = 17.5%
The weighted-average contribution margin ratio = Weighted contribution margin ratio for Sporting Goods + Weighted contribution margin ratio for Sports Gear = 19.5% + 17.5% = 37%.
