**Let x = the number of mezzanine tickets sold**

**Let 3x + 336 = the number of balcony tickets sold**

**Let x + 3x + 336 + 256 = the number of main floor tickets sold**

**56(4x + 592) + 31(3x + 336) + 30x = 75,145**

**224x + 33,152 + 93x + 10,416 + 30x = 75,145**

**347x + 43,568 = 75,145**

**347x = 31,577**

**x = 91 mezzanine tickets**

**3x + 336 = 3(91) + 336 = 609 balcony tickets**

**4x + 592 = 4(91) + 592 = 956 main floor tickets**
