Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (9,200 units × $406.00)         $3,735,200.00
  Less: Variable Costs (9,200 × $201.00) $1,849,200.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $1,886,000.00
  Less: Fixed Costs                                     $876,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $1,010,000.00

Per Unit:
  CM per Unit = $406.00 − $201.00 = $205.00
  CM Ratio    = $205.00 ÷ $406.00 = 50.49%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $876,000.00 ÷ $205.00 = 4273.1707 → 4274 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $876,000.00 ÷ 50.4926% = $1,734,907.32
