In order to average at least 20 points in 3 games, George must score at least 60 points.
He's already scored 38 points, so he needs
to score at least 60 - 38 = 22 points in the 3rd game.

make it into an inequality.
(21+17+x)/3 ≤ 20
after solving for x, you get x ≤ 22
(21+17+x)/3 ≤ 20
after solving for x, you get x ≤ 22
