How much would I be making at schnucks?

Well, most likely you wouldn't know for sure but can you please try to give me an estimate of how much I would be making in a Year. I'm 15 years old now but when I turn 16 in july i'm getting a job at schnucks as a bagger or customer service person I will be working part time for 3 months (or 90 days) and after that they will put me on full time, so can you please give me an estimate of how much I wil be making a year. Also I'm in SAINT LOUIS MISSOURI
