If exactly 400 people sign up for a charter flight, Leisure World Travel Agency charges $700/person. However, if more than 400 people sign up for the flight (assume this is the case), then each fare is reduced by $1 for each additional person. ? Determine how many passengers will result in a maximum revenue for the travel agency. What is the maximum revenue? What would be the fare per passenger in this case? ? Hint: Let x denote the number of passengers above 400. Show that the revenue function R is given by R(x) = (400 + x)(700 - x). ?
