Andrew has a mean score of 18 points per game in his four basketball games of the season.
Total points = 4*18 = 72
-------------------------------
How many points must he score in his next game to raise his mean score to 20 points per game?
Total points needed = (72+x)/5 = 20
72+x = 100
x = 28 (# of points needed on the 5th test)
==========================
