b. Contribution margin = $436,100
c. Operating income = $318,500
Explanation:
The formula of Manufacturing margin , Contribution margin & operating income is shown below. Along with it, the computation is also made.
Manufacturing margin = Sales - Variable cost of goods sold
= $490,000 - $220,500
= $269,500
Contribution margin = Sales - Variable selling and administrative expenses
= $490,000 - $53,900
= $436,100
Operating income = Contribution margin - (Fixed manufacturing costs + Fixed selling and administrative expenses )
= 436,100 - $(83,300 + 34,300)
= $318,500
Thus, a. Manufacturing margin = $269,500
b. Contribution margin = $436,100
c. Operating income = $318,500
