You can put this solution on YOUR website!
(172+150+148+162+X)/5=160
(632+X)/5=160 NOW CROSS MULTIPLY
632+X=800
X=800-632
X=168 IS THE MINBIMUM SCORE FOR THE LAST GAME TO HAVE AN AVERAGE OF AT LEAST 160.

---------------
Let the score on the fifth game be "x".
EQUATION:
(172+150+148+162+x)/5 = 160
637 + x = 5*160
x = 800-637
x = 163
He needs a score of at least 163 on the 5th game.
