Final answer:
The total balance after one month is $406.
Step-by-step explanation:
To calculate the total balance after one month, we need to consider the interest charged on the remaining balance.
Step 1: Calculate the interest charged for one month
Interest = Balance × (Annual Interest Rate / 12)
Interest = $600 × (0.12 / 12) = $6
Step 2: Subtract the payment made from the balance
Remaining Balance = Previous Balance - Payment Made
Remaining Balance = $600 - $200 = $400
Step 3: Add the interest to the remaining balance
Total Balance After One Month = Remaining Balance + Interest
Total Balance After One Month = $400 + $6 = $406
Therefore, the total balance after one month is $406.
