+84+-+%28+12+%2B+15+%29+=+84+-+27+
+84+-+%28+12+%2B+15+%29+=+57+
There are 57 remaining games
Let +x+ = the number of the remaing games
must be won to have 60% winning average
for the year
-------------------------------------------
+%28+12+%2B+x+%29+%2F+84+=+.6+
+12+%2B+x+=+50.4+
+x+=+38.4+
-----------------------
+%28+38.4%2F57+%29%2A100+=+67.37+
67.37% of remaining games must be won
to have a 60% winning average for the season
