Answer:
$6,400
Step-by-step explanation:
On December 31, year 1, 4 months has been passed so, the revenue of 4 months should be recognized at this date. The payment was recorded as unearned revenue on September 1 using following entry.
September 1,
Dr. Cash $19,200
Cr. Unearned Revenue $19,200
The revenue account will be credited by the 4 months revenue amount and unearned revenue account will be debited to reduce the amount by the four month accrual.
Total Unearned revenue = $19,200
Revenue for four months = $19,200 x 4/12 = $6,400
