question about cost

Hi, I'm a prospective OOS student from texas, and after using the net price calculator, my cost came out to be around 48k. I know this is already less expensive than most OOS schools, but my parents are saying they cant afford to pay that. Can anyone break down how I would pay this, because I'm guessing my parents would not be paying 48k straight out of pocket and want to convince them. If someone is in a similar situation, some insight into your financials would be helpful. Thanks a lot!
