Ambiguous treatment of partner's loan interest in profit calculation Steps:

• Profit before appropriation is $24,000; appropriation includes salary and residual sharing, but loan interest treatment (expense already deducted or appropriation to deduct) is unspecified.
• If interest ($50,000 × 5$2,500) already deducted, then deduct salary $14,000 from$24,000 = $10,000 residual, Brian's share$5,000.
• If interest not deducted, then deduct interest $2,500 + salary$14,000 from $24,000 =$7,500 residual, Brian's share $3,750.
• John's $5,000 drawings are advances against his share, not affecting residual calculation; no match to options.
