Step-by-step explanation:
The question given revolves around the calculation of operating income for Robusta Coffee Importers using the contribution margin income statement format for October. First, we calculate the contribution margin by subtracting all the variable costs from the sales. Variable costs include direct materials, direct labor, and variable manufacturing overhead (MOH) per unit.
Total Sales = 7000 units * $45/unit = $315,000
Total Variable Costs = ($10 + $2.50 + $7.50) * 7000 units = $140,000
Contribution Margin = $315,000 minus $140,000 = $175,000
Total Fixed Costs = $140,000 (Manufacturing) + $20,000 (Selling & Admin) = $160,000
Operating Income = Contribution Margin minus Total Fixed Costs = $175,000 minus $160,000 = $15,000
So, the operating income earned in October is $15,000
