Answer:
$12,000
Step-by-step explanation:
the initial journal entry to record this transaction would be:
Dr Installment accounts receivable 200,000
Cr Land 140,000
Cr Deferred gross gain 60,000
the journal entries to record the first payment
Dr Cash 40,000
Cr Installment accounts receivable 40,000
Dr Land 28,000
Dr Deferred gross gain 12,000
Cr Revenue 40,000
Since $40,000 represents 20% of the land's total value, the same proportion must be kept when recording land cost and deferred gross gain.
