Answer:
unearned service revenue 7,500 DEBIT
service revenue 7,500 CREDIT
Explanation:
the job is complete on July 31th
so we write-off the unearned service reveue
and we recognize the service revenue for the whole amount of the contract
The cash receipt occurs on March 1st so w edon't haveto post anythign related to cash on July 31th.
the unearned revenue account is used first because the business has the obligation of perform the job or return the cash. So it is a liablity until the job is completed
