I got C's in math throughout high school. Just hated it. In college I only had to take one Math Class, got a B- and Im done with it. Either way, she'll be fine.
I'd say ask her what she feels would be best for her future and make sure to take that into consideration and what her reasoning for doing poorly in the class is. Also find out if she got a 69.8 or a 79. The grade C tells you very little about her actual performance/understanding of the material.
