Most colleges and universities in the US provide a financial aid package. Your total aid will be a combination of scholarships and student loans. Take a look at the https://studentaid.ed.gov/sa/fafsa for more details. You'll also find links to scholarship websites.
If you are hard working and self motivated, you can also take a look at getting college credit for courses by testing out of them through DSST or CLEP exams. By testing out of your general education courses, you can significantly reduce your university bill and speed your way to a degree more quickly. Should you choose that path, check with your university on which CLEP/DSST courses they accept for credit.
