Answer:
Contribution margin = $200,000
Explanation:
As per the data given in the question,
Contribution margin = Sales - Variable expense
Number of books = $880,000 ÷ $55
=16,000
Gross margin = 340,000
Variable selling expenses = 16,000 × $6
=$96,000
Variable administrative expense = $880,000 × 5%
=$44,000
Total = $96,000 + $44,000
= $140,000
Contribution margin = $340,000 - $140,000
= $200,000
