Did not get an answer.  The reasoning behind this question is to observe how the answering person utilizes logic and somewhat common sense.  They allowed 20 minutes to solve the problem and I will admit it took me the entire time allowed, but I did get the correct answer.

The answer-

88 children at $.50 (fifty cents) each = $44.00

2 women at $3.00 (three dollars) each = $6.00

10 men at $5.00 (five dollars) each = $50.00

Total attendees=100

Amount received= $100.00

Jane, that is a long ways  from 100 attendees.
