Final answer:
The journal entry to replenish the petty cash fund should include a debit of $20 to travel expenses, a debit of $15 to office supplies, and a credit of $35 to cash. This reflects the vouchers used and the cash balance to bring the petty cash fund back to its original total of $200.
Step-by-step explanation:
The student's question relates to the adjustment of the petty cash fund in accounting. Upon inventory of the petty cash, it comprises of travel expense voucher for $20, office supply voucher for $15, and coins and banknotes totaling $170. The total amount in petty cash is expected to be $200; which means the sum of the vouchers and the coins and banknotes should equal this total. Since the vouchers represent expenses that have reduced the fund's cash on hand, the following journal entries would be made to replenish the petty cash to its set amount:
- Debit Travel Expenses $20
- Debit Office Supplies $15
- Credit Cash $35
The debit entries increase the expense accounts while the credit entry reduces the cash account, acknowledging that cash has been spent on travel and office supplies filling up the petty cash fund to the original total of $200.
