Matrices 4.a.ii ? anyone?

I got the answer as 3100 not 3200

Calculation: Since it asks for people who attend their SECOND game, they must have attended the first one too..

a1= [2000] D
      [1000] S

this game
       D        S
G= [1.2   -.03] D
     [0.2   0.70] S   Next game

so for them to attend their 2nd game, its either DtoD or StoS :    2000 x 1.2 + 1000 x 0.7 = 3100

someone tell me why I'm wrong/right ?

the question asked for attendance matrix for the second game, i.e. how many attending the second game, not THEIR second game
