Final answer:
The correct weighted-average unit contribution margin is $5.00, option e) None of the answers is correct.
Step-by-step explanation:
The weighted-average unit contribution margin is a measure of how much each unit sold contributes to covering the fixed expenses of the company. To calculate the weighted-average unit contribution margin, we need to find the weighted-average contribution margin for each type of shoe, Plain and Fancy.
Contribution margin for Plain shoes:
(Unit selling price - Variable cost per unit) x Percentage of unit sales for Plain shoes
Contribution margin for Fancy shoes:
(Unit selling price - Variable cost per unit) x Percentage of unit sales for Fancy shoes
Weighted-average unit contribution margin:
(Contribution margin for Plain shoes + Contribution margin for Fancy shoes)
Therefore, the weighted-average unit contribution margin can be calculated as follows:
Plain shoes: ($20.00 - $15.00) x 0.6 = $3.00
Fancy shoes: ($31.00 - $26.00) x 0.4 = $2.00
Weighted-average unit contribution margin:
= $3.00 + $2.00
= $5.00
The correct weighted-average unit contribution margin is $5.00, option e) None of the answers is correct.
