You can put this solution on YOUR website!
Let +n+ = the number of days that pass
The +3+ friends each made +4+ bags of tea
------------------------------------------
For +1+ of the +3+ friends:
+192+%2F+3+=+4%5E%28+n%2F10+%29+
--------------------------
+64+=+4%5E%28+n%2F10+%29+
+64+=+4%5E3+
+n%2F10+=+3+
+n+=+30+
The other 2 friends are making tea bags at the same rate,
so I would say:
30 days pass before 192 bags are made
