Answer :
Answer: Decrease by $9,800
Explanation:
It is shown that fees of $9,800 were earned during the month from clients who had paid in advance. Unearned fees are liabilities because they represent revenue that a company made for services it has not delivered yet.
When the company delivers the service like these ones just did, they will reduce this liability because they have now earned this revenue by delivering the service.
Omega will therefore reduce their unearned fees account by $9,800.
