According to this article that is mostly about all spending that event goers pay per home game, it says that for football games altogether fans pay about 5 million per home game, but that includes tickets, shopping, lodging, food and travel.
Further down it discusses a $500,000 buyout for Presbyterian, and that the 2 cancelled games, UF would receive insurance payouts for lost revenue of 7.8 million, or a ballpark or 3.9 million per game.
I also found another article about the 2009 per game operating revenue, which at the time was about 2.3 to 2.5 million per game, which would have been what the school actually gained from each game back then. There was not much difference between who we played except FSU and UT games brought in 2.5 per game

Considering inflation etc, 3.5 to 4 million per home game would be realistic.
looking at some other sites, looks like all ticket sales for all sports equals about 24.5 million on their own.
That would be 3.5 for 7 home games, assuming every ticket for every other sport was free.
So 3.5 to 4 mil per home game with ticket sales plus food and merch sales is probably in the ballpark.
