If a stadium has 15,000 seats sold at $10.00, $12.50, and $15.00 equally distributed in three sections, how much can be made if the stadium sells out?

  $187,500

Step-by-step explanation:

There must be 15,000/3 = 5,000 seats in each section. Then the total revenue can be ...

  5000·$10.00 + 5000·12.50 + 5000·15.00 = 5000·($10 + 12.50 +15.00)

  = 5000·$37.50 = $187,500

Stadium revenue can be $187,500 if all seats are sold.
