<PRE><B>Question 105739</B>
Let x: number of student tickets sold
    400-x: number of adult tickets sold


Since the cost of a student ticket is $2, and an adult ticket costs $3:


2x: money earned from student tickets
3(400-x): money earned from adult tickets


Equation: 1050 = 2x + 3(400-x)
          1050 = 2x + 1200-3x
          1050 = -x + 1200
          1050 - 1200 = -x
          -150 = -x
          -x = -150
          x = 150


400 - 150 = 250


Student tickets: 150
Adult tickets: 250


By the way, this is jermz69.
