The " eight " people is confusing- it just
means that it is a large group, I guess
-----------------
The $139.50 is the cost before the
gratuity and taxes ( I think ?? )
-------------------------------
They say the tax gets tacked on first
Cost of meal + tax =
+139.5+%2B+.06%2A139.5+
+139.5+%2B+8.37+=+147.87+
---------------------------
Then the gratuity gets tacked on:
So is it 18% of the meal + tax ?
I think so.
-----------------------------
+147.87+%2B+.18%2A147.87+=+147.87+%2B+26.62+
+147.87+%2B+26.62+=+174.49+
The total bill is $174.49
----------------------
