Step 1: Arrange all 5 prices from lowest to highest.
$11 964 even
Step 4: Verify the other even numbers in the list are not third lowest.
$11 964 (last digit 4, even) -- position 1, not third.
$11 976 (last digit 6, even) -- position 2, not third.
$12 480 (last digit 0, even) -- position 4, not third.
$12 804 (last digit 4, even) -- position 5, not third.
Only $12 048 is both third lowest AND even.
