Partnership Retirement Settlement Calculation Steps:

• Identify M's capital balance: $7000.
• Note goodwill valuation: $4000 total, but profit-sharing ratio unspecified.
• Account for asset takeover: Motor vehicle valued at $5000, deducted from settlement.
• Calculate total due: Capital + M's goodwill share - asset value, but share unknown.

Not enough information: Profit-sharing ratio or goodwill treatment for M missing, preventing exact calculation.

Final answer: Not enough information.
