Contribution Margin represents the profit an organisation can generate from the sale of a product. in order to calculate, the variable costs are deducted from the revenue from sale.

The formula for Contribution margin = Sales- the cost of goods sold - variable selling expense.

Selling Price = $65

Reported ales = $910,000

First, we determine the number of books sold in the first quarter

= $910 000/ $65 = 14 000 books

Second, since the store sold 14,000 books in the first quarter, the total variable selling cost for the books sold

= total books sold x the variable selling expense per book

= 14,000 x $4 = $56,000= total variable selling expense

Third, since the store sold 14,000 books in the first quarter, the total variable administrative cost for the books sold

= total books sold x the variable administrative expense per book

= 14,000 x $3 = $42,000= total variable Administrative expense

Four, determine the contribution margin as follows:

Sales - cost of goods sold - variable selling expense - variable administrative expense

= $910,000-$560,000- $56,000-$42,000= $252,000
