How old do you have to be to work at target?

See I am going to be 16 in september. There is a target right by my school and I was wondering how old I would have to be to work there. I end my last class at 1:20 so maybe I could work there from like 1:45 to 5:45 or something. Please help because I really need this money for my classes and books lol
Update: thank you ppl!!! lol
