Small carpet repair cost?

I live in a dorm room right now, at one of the ASU campuses, and there are several bleach and dye stains in the carpet in the bathroom area of our dorm suite from my roommate and I. It's nothing HUGE but the bleach stain is about the size of a child's fist. The dye spots are light and pretty small, but still noticeable. How much does getting small carpet fixes like that cost? It's super cheap-o carpeting, clearly, nothing too pricey. Does anyone know from experience how much the repair actually costs or how much ASU will charge us upon move-out for the stains??
