Surely, the problem is formulated incorrectly, leaving to a reader to guess 
what $27 are - one time payment or a payment for each person of a group.


Math problems are NEVER presented/formulated this way.


Only totally &nbsp;&nbsp;{{{highlight(highlight(incompetent))}}} &nbsp;&nbsp;people formulate problems this way as it is done in this post - 
- those who do not distinct a Math problem from a third-rate puzzle.
