+1100+%2F+%28+1+%2B+99%2Ae%5E%28-.3x+%29+%29+=+275+
+1+%2B+99%2Ae%5E%28-.3x+%29+=+1100%2F275+
+99%2Ae%5E%28-.3x+%29+=+4+-+1+
+e%5E%28+-.3x+%29+=+1%2F33+
Take the natural log of both side
+-.3x+=+ln%281%29+-+ln%2833%29+
+-.3x+=+-3.4965+
+x+=+11.655+
---------------------
check answer:
+1100+%2F+%28+1+%2B+99%2Ae%5E%28-.3%2A11.655+%29+%29+=+275+
+1100+%2F+%28+1+%2B+99%2Ae%5E%28-3.4965+%29+%29+=+275+
+1100+%2F+%28+1+%2B+99%2A.030303+%29+=+275+
+1+%2B+3+=+1100%2F275+
+4+=+4+
OK
