For bottle with 25% water:
+2%2A.25+=+.5+ gallons of water
For bottle with 15% water:
+3%2A.15+=+.45+ gallons of water
---------------------------
The FRACTION of water in the mixture is:
+%28+.5+%2B+.45+%29+%2F+%28+2+%2B+3+%29+=+.95%2F5+
---------------------------------
The PERCENT of water in the mixture is:
+%28+.95%2F5+%29%2A100+=+19+
19% of the mixture is water
