Profit margin requires sales revenue, which is not directly provided

Steps:

• Identify that profit margin = (net profit / sales revenue) × 100%.
• Note net profit = $16,000, but sales revenue is missing.
• Cost of sales ($80,000) and expenses ($40,000) allow deriving sales = $16,000 +$80,000 + $40,000 =$136,000.
• However, since sales is not explicitly given, the information is insufficient for standard calculation without assumptions.

Why the correct option is correct:

• Not applicable; no option matches the derived 11.76% ($16,000 /$136,000 × 100%).

Why the others are wrong:

• A: Assumes sales ≈ $100,000, ignoring derivation.
• B: Equals profit / cost of sales (16,000 / 80,000), confusing margin with markup.
• C: Approximate but incorrect; yields $14,280 profit on$136,000 sales.
• D: Assumes unrealistically low sales ≈ $60,000.

Final answer: Not enough information.
