Final answer:
The correct amount of Service Revenue to be reported in the July income statement is $21,320.
Step-by-step explanation:
To determine the correct amount of Service Revenue to be reported in the July income statement, we need to adjust the Unearned Service Revenue based on the contracts earned. According to the information provided, $4,810 of Unearned Service Revenue has been earned in July. Therefore, we need to reduce the Unearned Service Revenue by $4,810 and increase the Service Revenue by the same amount.
The original Service Revenue reported on the trial balance is $16,510. By adding the earned revenue of $4,810, the correct amount of Service Revenue to be reported in the July income statement is $21,320.
