So I know I'm off somewhere just don't know where I been close just not right yet.

I found the following:

1. Service revenue earned but not billed $915 - you have this in A/R. Since it wasn't billed, you want it in an Earned Revenue Receivable account, also an asset.
2. Prepaid rent expired is $500. They are not saying that the final balance is 500, rather that $500 should be expensed. Also affects rent expense account.
3. Check your Service Revenue. You are correct that $1410 is the final balance, meaning there was an adjustment for $1450. It looks like your credit was made for $1410 instead of $1450.
4. Your rent expense should have changed due to the portion of prepaid rent that was expensed.

Please let me know if you have any questions. Thanks.

Thank you for the help.
