Question

Quizplus · Accepted Answer

The total contribution margin under variable costing is calculated by subtracting all variable costs from sales. Here, variable costs include raw materials used, direct labor, variable factory overhead, and variable selling and administrative expenses. Sales are given as $117,000. The variable costs are: Raw materials used = $37,500, Direct labor = $63,000, Variable factory overhead = $25,500, and Variable selling and administrative = $4,500. Adding these variable costs gives a total of $130,500 in variable costs. Subtracting this from sales ($117,000 - $130,500) does not directly give the contribution margin, indicating a calculation error in the explanation. The correct approach is to first correctly calculate the total variable costs and then subtract this from the sales to find the contribution margin. The correct calculation should consider the sales amount and correctly subtract the sum of all variable costs provided to find the contribution margin.
