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
