40 (4) + 12 (2) ≤ 500
160 + 24 ≤ 500
184 ≤ 500
184 is less than 500.
because I was not sure if you had 9 adults instead of 2, this is the answer:
40 (4) + 12 (9) ≤ 500
160 + 108 ≤ 500
268 ≤ 500
268 is less than 500

Graces expect her Favorite team can win 99 games.
Step-by-step explanation:
Total games needs to be played = 162
So far graces favorite team won 11 games and lost 7 games
