Answer:
$2.73
Step-by-step explanation:
Contribution margin:
Red = Unit Contribution margin × Sales Mix
= $ 2.90 × 2,100
= $6,090
Black = Unit Contribution margin × Sales Mix
= $ 3.00 × 700
= $2,100
Total contribution margin = Red + Black
= $6,090 + $2,100
= $8,190
Total sales mix = 2,100 + 700
= 3,000
Weighted CM:
= Total Contribution Margin ÷ Sales Mix
= $8,190 ÷ 3,000
= $2.73
