Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (33,500 units × $1,190.00)         $39,865,000.00
  Less: Variable Costs (33,500 × $807.00) $27,034,500.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $12,830,500.00
  Less: Fixed Costs                                     $1,113,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $11,717,500.00

Per Unit:
  CM per Unit = $1,190.00 − $807.00 = $383.00
  CM Ratio    = $383.00 ÷ $1,190.00 = 32.18%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $1,113,000.00 ÷ $383.00 = 2906.0052 → 2907 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $1,113,000.00 ÷ 32.1849% = $3,458,146.21
