Does this girl like me?

Okay. I'm in this summer enrichment program and there is a girl that sits next to me. I could see her look at me often from the corner of my eye. She asked me to throw something away for her; I did. We found out we like the same music, and finally, at dismissal, she randomly said something to me about wanting a salad (leftover lunches) but they were all gone. She's normally quiet. I kinda like her too so does she like me or is it just wishful thinking? As for age, I'm 15. She's 15 or 16.
