Antonio is in a bowling league. His goal is to score an average of at least 100 points per game. His scores so far are 105,95,97
Vilka [71]
The answer would be 11.
He’s playing 6 games to meet his goal which is 600. Adding 105+95+97+82+110 you’ll have 489 total points. You’ll then subtract 600-489 which will equal to 111.
