Final answer:
To determine the true cash balance, a bank reconciliation is prepared. The true cash balance is calculated by adjusting the unadjusted cash account balance for items like deposits in transit, outstanding checks, credit memos, and service charges. Adjusting entries are then recorded to correct the unadjusted book balance.
Step-by-step explanation:
a. Bank Reconciliation
To determine the true cash balance, we need to prepare a bank reconciliation. Here are the steps:
1. Start with the unadjusted cash account balance of $15,200.
2. Add the deposit in transit of $2,400. This represents a deposit that the company made, but it has not yet been recorded by the bank.
3. Subtract the outstanding check of $6,690. This represents a check that the company issued, but it has not yet been cashed by the recipient.
4. Add the credit memo of $30. This represents interest earned that was recorded by the bank, but not yet recorded by the company.
5. Subtract the service charge of $20. This represents a fee charged by the bank for services.
The true cash balance is calculated as follows: $15,200 + $2,400 - $6,690 + $30 - $20 = $10,920.
True Cash Balance: $10,920
b. Adjusting Entries
To correct the unadjusted book balance, we need to record adjusting entries. Here are the entries:
1. To record the deposit in transit: Debit Cash, Credit Deposits in Transit for $2,400.
2. To record the credit memo: Debit Interest Income, Credit Cash for $30.
3. To record the outstanding check: Debit Accounts Payable, Credit Cash for $6,690.
4. To record the service charge: Debit Service Charge Expense, Credit Cash for $20.
These adjusting entries will bring the unadjusted book balance in line with the true cash balance.
