Your favorite radio station, WCPM, is having a contest. The DJ poses a question to the
listeners. If the caller answers correctly, he or she wins the prize money. If the caller
answers incorrectly, $20 is added to the prize money and the next caller is eligible to
win. The current question is difficult, and no one has won for two days.
a. Lucky you! Fourteen people already called in today with incorrect answers, so
when you called (with the right answer, of course) you won $735! How much was
the prize worth at the beginning of the day today?
