Answer:
Contribution margin per unit: $42.9
Total contribution margin: $8,580
Step-by-step explanation:
The contribution margin per unit is calculated by calculating the total contribution margin, which is basically the total sales, minus the costs of production, in this cae we have that we sold:
60 regular chairs
140 executive charis
Now the total in sales is:
Regular sales: $6,000
Executive chairs: $23,800
The variable cost of each is:
Regular chairs: $3720
Executive chairs: $17,500
We add up the sales and withdraw from it the total variable cost:
29,800-21,220=8,850
The total contribution margin is equal to $8850.
And the contribution margin per unit is given by dividing the total contribution margin by the number of units sold:
8850/200= 42.9
So the contribution margin per unit is 42.9 dollars.
