What is the pattern?
Are we saying that the ticket price can only be changed in increments of $5? If so you will have 2 different maximums.
Does a $5 decrease always add another 2000 consistantly?
A professional basketball team plays in a stadium that holds 23,000 spectators. With
ticket prices at $60, the average attendance had been 18,000. When ticket prices were
lowered to $55, the average attendance rose to 20,000. Based on this pattern, how should
ticket prices be set to maximize ticket revenue?
