Weighted average Contribution margin = (Selling Price per unit - Variable Cost per unit) of the 3 umbrella / Number of Unit
Weighted average Contribution margin = [($20-$9)*2 + ($17-$12)*3 + ($9-$6)*5 ] / (2+3+5)
Weighted average Contribution margin = [$22 + $15 + $15] / 10
Weighted average Contribution margin = $52 / 10
Weighted average Contribution margin = $5.2
So, the weighted average contribution margin per unit for Tonto is $5.2
