Final answer:
The correct general journal entry to record Yin's transaction is to debit Cash $690, credit Income from Repairs $600, and credit GST Collected $90 (option D). This aligns with the sales amount and the separate collection of GST.
Step-by-step explanation:
The correct journal entry to record the transaction where Yin repaired Yan's computer and charged her $690, which includes GST of 15%, is to account for the sales amount (excluding GST), and the GST collected separately (option D). The entry would be as follows:
- Debit Cash $690 (the total amount received)
- Credit Income from Repairs $600 (the income excluding GST)
- Credit GST Collected $90 (the GST amount at 15% of $600)
This entry reflects that Yin has received cash and has an obligation to remit the GST to the tax authorities, and recognizes the income earned from the repair service.
