Angela booked a band for tonight. she decided to use yield management pricing and set three ticket prices $17.50, $15.00, and $12.50. fans bought 3,000 seats in each section. what was the revenue for the event?

Given:
ticket prices $17.50, $15.00, and $12.50.
Fans bought 3,000 seats in each section

This means that 3,000 seats were bought from each price assuming that each price represents a section. Thus, there are 3 sections for a total of 9,000 seats sold. 

17.50 x 3000 = 52,500
15.00 x 3000 = 45,000
12.50 x 3000 = 37,500
total                135,000

The revenue for the event is $135,000.

Yield management pricing is defined as the "variable pricing strategy, based on understanding, anticipating and influencing consumer behavior in order to maximize revenue or profits from a fixed, time-limited resource" 

The revenue we computed is the best possible maximum revenue that the event can garner that satisfies both supplier and buyer. Had Angela maintained a single price, only a section nearest to the stage will be filled because people will not find it worthy to buy a ticket that will not let them see the band up close. This will lead to a lesser revenue.
