Answer:
Leon's gain = $65,000
Step-by-step explanation:
Total consideration received by Leon = $75,000 (cash) + $25,000 (artwork) + $20,000 (loan assumed by buyer) = $120,000
Leon's total costs = $50,000 (equipment's basis) + $5,000 (selling expenses) = $55,000
Leon's gain = total consideration received - total costs = $120,000 - $55,000 = $65,000
