Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (32,600 units × $666.00)         $21,711,600.00
  Less: Variable Costs (32,600 × $333.00) $10,855,800.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $10,855,800.00
  Less: Fixed Costs                                     $787,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $10,068,800.00

Per Unit:
  CM per Unit = $666.00 − $333.00 = $333.00
  CM Ratio    = $333.00 ÷ $666.00 = 50.00%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $787,000.00 ÷ $333.00 = 2363.3634 → 2364 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $787,000.00 ÷ 50.0000% = $1,574,000.00
