Don't worry about the lack of weighting, colleges discount for that anyway.
She still has an opportunity to pull that grade up and you might consider tutoring for this last quarter and exams. Beyond that, she can absolutely get into a good school with a low grade in an AP class. Maybe not the absolute most competitive (though still worth a shot) but there are plenty of great colleges out there.
