Final answer:
The information provided is insufficient to determine the remaining cost after 72 payments for the 2021 Subaru Impreza. More specific financial details about the loan are necessary for an accurate calculation.
Step-by-step explanation:
To determine the cost remaining after 72 payments for the 2021 Subaru Impreza, one would typically need to know the initial loan amount, the interest rate, the number of total payments, and the payment amount. However, with the information available, which appears to be payment history and not the actual terms of a car loan, it is not possible to accurately answer the student's question. Accurate calculation would require more specific financial details regarding the car loan.
For a precise calculation, we would need to know how much was initially financed, the annual percentage rate (APR), and if any down payment was made. Additionally, understanding if the payments were equal and if there were any additional fees or early repayment penalties would also be important. We cannot determine the remaining cost without these details.
