Answer:
9 games
Step-by-step explanation:
1st (y = 4.45x+85)
2nd (y = 13.89x)
4.45x+85 = 13.89x
-4.45x -4.45x
85 = 9.44x
85/9.44 = x
x = 9
2+1/3n=8 is the answer, I believe.
90 + 122 + 4x + 19 + 9x - 8 + 7x - 3 = 540
220 + 20x = 540
-220 -220
--------------------------
20x = 320
/20 /20
----------------
x = 16
