Answer:
$10,900
Step-by-step explanation:
The computation of net operating income (loss) for the month under variable costing is shown below:-
Sales = Selling price × Units sold
= $116 × 8,600
= $997,600
Variable cost = (Direct material + Direct labor + Variable manufacturing overhead + Variable selling and administrative expenses) × Units sold
= ($19 + $61 + $7 + $11) × 8,600
= $98 × 8,600
= $842,800
Contribution Margin = Sales - Variable cost
= $997,600 - $842,800
= $154,800
Fixed cost = Fixed manufacturing overhead + Fixed selling and administrative expense
= $135,000 + $8,900
= $143,900
Net operating income = Contribution Margin - Fixed cost
= $154,800 - $143,900
= $10,900
Therefore for computing the net operating income we simply applied the above formula.
