Answer:
Unearned membership revenue of $9,000
Explanation:
The sales on credit during January 2017 was valued at $12,000 ($200 x 60).
In March 2017, customers paid $3,000, leaving the balance of $9,000 outstanding.
Since the season for which sales and collections were made starts March 1, 2017, when reporting the financial statements for the period ending March 31, 2017, the Membership Revenue would be $3,000 only and the balance $9,000 would be reported as Unearned Membership Revenue in the Balance Sheet with a further $9,000 reported in the Accounts Receivable to balance the records.
This shows that Unearned Membership Revenue of $9,000 is the only valid statement.
