4x/15 = 60/x
4x^2 = 900
x^2 = 225
x = 15
2.00+1.50= 3.50.
3.50x8= 28.00
I'm assuming they each paid 41.00 dollars for two games,
41.00x8= 328.00
328.00+28.00= $356.00
Hope this is correct and/or it helps!
Sorry, didn't realize my mistake.

Please mark me brainless :)
F(x) = x(x -1)
f(3) = 3*2 = 6
f(6) = 6*5 = 30
so f(f(3)) = 30 . . . . . selection A
