Answer:
$2.63
Explanation:
The computation of the weighted average contribution margin is shown below:-
Contribution margin = Selling price - Variable costs
For cheeseburger
= $4.75 - $2.00
= $2.75
For regular hamburger
= $4.25 - $1.75
= $2.5
Weighted average Contribution margin = Respective Contribution margin × Respective mix
= ($2.75 × 3) ÷ 6 + ($2.5 × 3) ÷ 6
= $1.38 + $1.25
= $2.63
