Final answer:
The total service revenue in the given scenario increases by $4,000, which is the amount of unearned service revenue that has been recognized as earned.
Step-by-step explanation:
The question is asking about the impact of two separate transactions on total service revenue.
- The first transaction involves recognizing $4,000 of unearned service revenue as earned.
- The second transaction is the collection of $3,000 cash for service revenue that had been previously accrued.
In the first transaction, the initially unearned revenue is now recognized as earned, thus increasing the total service revenue by $4,000.
However, the collection of $3,000 does not impact the total service revenue, as this was already recognized in revenues when it was accrued.
Therefore, only the $4,000 will increase the total service revenue.
