+%28+n+%2B+n%2B+2+%2B+n+%2B+4+%2B+83+%29+%2F+4+%3C=+82+
+%28+3n+%2B+89+%29+%2F+4+%3C=+82+
+3n+%2B+89+%3C=+328+
+3n+%3C=+239%0D%0A%7B%7B%7B+n+%3C=+79.667+
And
+%28+3n+%2B+89+%29+%2F+4+%3E=+80+
+3n+%2B+89+%3E=+320+
+3n+%3E=+231+
+n+%3E=+77+
If +n+ is an odd integer, then
The lowest score is either 77 or 79
