The owner of a luxury motor yacht that sails among the 4000 Greek is lands charges $848/person/day if exactly 20 people sign up for the cruise. However, if more than 20 people sign up (up to the maximum capacity of 100) for the cruise, then each fare is reduced by $8 for each additional passenger. Assuming 20 people sign up for the cruise, determine how many passengers will result in the max revenue. What is the max revenue? What is the fare per passenger?
