Math, microeconomics or criminal justice
A+S= 321, multiply by 3.5 then subtract 2nd equation to eliminate one variable
A= number of adult tickets, S= number of student tickets
3.5 = $3.50, 2.5 = $2.50
3.5A + 3.5S= 3.5(321)
3.5A + 2.5S = 937.5
S = 3.5(321) - 937.5 = 1123.5-186 = student tickets
A = 321-186 =135 adult tickets
