You can put this solution on YOUR website!
Let +t+ = the total bill
+t%2F10+ = what each one would have paid with 10 people
+t%2F9+ = what each one paid after one left
---------------------
+t%2F9+-+t%2F10+=+.6+
+t%2F9+-+t%2F10+=+6%2F10+
Multiply both sides by +90+
+10t+-+9t+-+54+
+t+=+54+
The bill was $54
---------------
check:
+t%2F9+-+t%2F10+=+.6+
+54%2F9+-+54%2F10+=+.6+
+6+-+5.4+=+.6+
+.6+=+.6+
OK
