Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (35,300 units × $524.00)         $18,497,200.00
  Less: Variable Costs (35,300 × $225.00) $7,942,500.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $10,554,700.00
  Less: Fixed Costs                                     $1,154,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $9,400,700.00

Per Unit:
  CM per Unit = $524.00 − $225.00 = $299.00
  CM Ratio    = $299.00 ÷ $524.00 = 57.06%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $1,154,000.00 ÷ $299.00 = 3859.5318 → 3860 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $1,154,000.00 ÷ 57.0611% = $2,022,394.65
