To fill in the missing new account balance for account 5, we can analyze the information presented:
**Account 5 Initial Information:**
- Old Account Balance: -10
- Transaction Amount: -20
To find the new account balance for account 5, we will calculate it using the old balance and the transaction amount:
\[
\text{New Account Balance} = \text{Old Account Balance} + \text{Transaction Amount}
\]
\[
\text{New Account Balance} = -10 + (-20) = -10 - 20 = -30
\]
This confirms the new account balance for account 5 is -30.
### Explanation of the Numbers for Account 5:
1. **-10** (Old Account Balance): This indicates that the account was overdrawn, which means the account holder owed the bank $10 or had a negative balance of $10 before the transaction occurred.
2. **-20** (Transaction Amount): This represents a withdrawal of $20 from the account. Since the account was already in the negative, this transaction further increased the negative balance.
3. **-30** (New Account Balance): This is the result after processing the transaction. It shows that after the withdrawal of $20, the account balance is now -$30, meaning the account holder now owes the bank an additional $20 compared to before the transaction.
Thus, all three numbers highlight the state of the account during and after the transactions, demonstrating how withdrawals affect an already negative balance.
