**Let x = the number of upper deck seats sold**

**Let y = the number of lower deck seats sold**

**x + y = 48,000 y = 48,000 - x**

**10.50x + 15.50y = 556,800**

**10.50x + 15.50(48,000 - x) = 556,800**

**10.50x + 744,000 - 15.50x = 556,800**

**-5x = -187,200**

**x = 37,440**

**y = 48,000 - x = 48,000 - 37,440**

**y = 10,560**
