Answer:
more than 22
Explanation:
last year average 21points per game
so they need at least 22 points per game to be better than last year average
to get 22 points per game average (for the first three game)
they need to score total = 22 × 3 games = 66 points
then, minus total score they need to goal
66 - 14 -30
= 22 point more to score
