32*2 is the maximum amount that we assume the basketball player can score. 64 is 7 away from 57 so we know that the basketball player scored 7 1 point. That means the basketball player scored 25 2 point shots.
What we did was find out the maximum possible score. Then we subtracted what score the basketball player got from the highest possible score. Now we find the difference of the scores. We notice that the two types of points has a difference of 1.
