Answer:
45.45%
Explanation:
The total selling price was $200,000 (paid on the date of the sale) + $900,000 (note received) = $1,100,000
Juan's cost of he land = $700,000 (basis) - $100,000 (mortgage) = $600,000
Juan's profit = $1,100,000 - $600,000
Juan's gross profit percentage = $500,000 / $1,100,000 = 45.45%
