Ok, got it.
I'll do it in two steps.
First
The fans come primarily to see the players, but they are also coming to see the coaches. Coaches don't count as much as players, let's say half as much.
So the average team has 13 players plus 4 coaches or 2 player equivalents. The at means the 2600 fans need to be divided by 15 , or 173 per player equivalent.
UConn has 10 scholarship players and 2 coaches, so that is 10, plus 2, or 14 player equivalents. Multiply by the factor of three, and you can allow in 7280 fans (plus the 100 for the other yeam.
But wait there's more.
The fans also come to see the cheer leaders. and the Dance squad. Some won't admit this. And some aren't interested. UConn has ten cheerleaders and 10 Dance team members ( I have no idea , I'm making this up)
But some other schools have fewer, or no cheer leaders. Many do not have a dance team. The average squad for other schools is six, total. Like coaches, they aren't worth as much as a player, but they are worth more than coaches. Each one is worth 1.618 times as much as a coach (that's the
Golden ratio, you can look it up) which mean they are worth as much as 0.809 players.
Other schools this have 13 + 2 + 6 x 0.809 = 19.854 player equivalents.
So the attendance is 130 per player equivalent.
So UConn has 10 + 2 + 16.18= 28.18 player equivalents so can allow in 11071. (Plus the 100 for the opposing team.)
