Answer:
The contribution margin decrease by $3,000
Explanation:
In this question, we have to apply the contribution margin formula which is shown below:
Contribution margin = Sales - variable cost
Where,
Sales = Selling price per pillow × number of pillows sold
= $25 × $1,200
= $30,000
And, the variable cost = Variable cost per pillow × number of pillows sold
= $15 × $1,200
= $18,000
So, the contribution margin equals to
= $30,000 - $18,000
= $12,000
Now due to material improvement,
The new Sales = Selling price per pillow × updated number of pillows sold
= $25 × $1,500
= $37,500
And, the variable cost = Variable cost per pillow × updated number of pillows sold
= $15 × $1,500
= $22,500
So, the new contribution margin equals to
= $37,500 - $22,500
= $15,000
So, the contribution margin decrease by $3,000 ($15,000 - $12,000)
