1 for 10 seems reasonable, assuming there is also a strict academic requirement for that privileged student. Even more points if it supports their housing and food plan.
If you fail out Timmy, he has to pay for tuition again thus paying for even more students. Or just charge the 10x upfront + normal tuition/year after that.
Further points if rich kids do household chores, cleaning, cooking etc for less privileged folks. Just strict academic requirement is not sufficient. Rich kids also have to remain in 95 percentile in academics. A further investigation committee need to be setup to investigate every year if rich kids are not using their influence to be among top students in their classes.
