But, (assuming the 2X price for out-of-state example) a school can offer 50% to an in-state vs 75% to out-of-state to equal total money out of pocket to the wrestler. So, the wrestling program save 1/4 of a scholarship by doing this.
Assuming total money out of pocket is equal:
20 in-state wrestlers at 50% = 10 total scholarships
13.3 out-of-state wrestlers at 75% = 10 total scholarships
This is how the school benefits from getting wrestlers to establish in-state residency ahead of time.
