Explanation:
If we want to persuade the college officials to permit themselves the cost of upgrading exercise facilities for non-athletes, we must think of a way to remunerate their effort, as students who are not on any team do not <em>bring revenue</em>.
And it is exactly the objective of the third paragraph.

That way <em>students who use the facility</em> will eventually <em>start using the snack bar</em>, too.
