Scenario 15-6 The concert promoters of a heavy-metal band, WeR2Loud, know that there are two types of concert-goers: die-hard fans and casual fans. For a particular WaR 2 Loud concert, there are 1,000 die-hard fans who will pay $150 for a ticket and 500 casual fans who will pay $50 for a ticket. There are 1,500 seats available at the concert venue. Suppose the cost of putting on the concert is $50,000, which includes the cost of the band, lighting, security, etc.

Refer to Scenario 15-6. How much additional profit can the concert promoters earn by charging each customer their willingness to pay relative to charging a flat price of $50 per ticket?
