Final answer:
To calculate the balance in Dora's register, subtract the total amount of deductions and add the total amount of deposits from the initial balance of $0.
Step-by-step explanation:
To calculate the balance in Dora's register, we need to keep track of the transactions and update the balance accordingly. Starting with an initial balance of $0:
- On 10/4, an automatic payment of $452.17 is deducted from the balance, leaving $-452.17.
- On 10/5, an ATM withdrawal of $120.00 is deducted from the balance, leaving $-572.17.
- On 10/9, a deposit of $510.11 is added to the balance, resulting in a final balance of $-62.06.
Therefore, the balance in Dora's register should be $-62.06.
