Barkley company sells two products, red cups and black mugs. barkley predicts that it will sell 2 comma 100 red cups and 700 black mugs in the next period. the unit contribution margins for red cups and black mugs are $ 2.90 and $ 3.00, respectively. what is the weighted average unit contribution margin? (round the final answer to the nearest cent.)

$2.73

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
