Seventh- and eighth-grade students participated in a tournament. Each contestant played each other contestant once. There were ten times as many eighth-grade students, but they were able to win only four-and-a-half times as many points as seventh graders.(adsbygoogle = window.adsbygoogle || []).push({});

How many seventh-grade students participated, and how many points did they collect?

Note: Assume one point for every win, and no drawn outcomes.
