Answer:
D) $125,000
Explanation:
The computation of the contribution margin is shown below:
= Sales revenue - variable cost of goods sold - variable selling and administrative expenses
= $500,000 - $300,000 - $75,000
= $125,000
The fixed cost expense should not be considered under the variable costing method, so ignored it.
Simply the contribution margin = Total revenues - total variable cost
Hence, the correct option is D.
