Answer:
Unitary contribution margin= $5 increase
Explanation:
Giving the following information:
Selling price= $275 per pair
The variable cost per boot is $250 and special stitching will add another $20 per pair to the cost.
To calculate the effect on income for each boot, we need to calculate the unitary contribution margin.
Unitary contribution margin= selling price - unitary variable cost
Unitary contribution margin= 275 - (250 + 20)
Unitary contribution margin= $5
