Final answer:
The finance charge on this loan is -$720, which means Anna saves $720 compared to the amount borrowed.
Step-by-step explanation:
To find the dollar amount of the finance charge on this loan, we need to calculate the total amount paid over the 3-year loan period and subtract the principal amount borrowed.
Step 1: Calculate the total amount paid over 3 years:
Monthly payment x Number of months = Total amount paid
$480 x 36 = $17,280
Step 2: Subtract the principal amount borrowed from the total amount paid:
Total amount paid - Principal amount = Finance charge
$17,280 - $18,000 = -$720
The finance charge on this loan is -$720, which means Anna saves $720 compared to the amount borrowed.
