Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (33,000 units × $655.00)         $21,615,000.00
  Less: Variable Costs (33,000 × $429.00) $14,157,000.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $7,458,000.00
  Less: Fixed Costs                                     $665,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $6,793,000.00

Per Unit:
  CM per Unit = $655.00 − $429.00 = $226.00
  CM Ratio    = $226.00 ÷ $655.00 = 34.50%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $665,000.00 ÷ $226.00 = 2942.4779 → 2943 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $665,000.00 ÷ 34.5038% = $1,927,323.01
