$4 x Advance tickets
$5.50 y sold at door
Equation for total investors
x - y = 15 .............1
Equation for amount raised
$4 x + 5.50 y = $440 .............2
Eliminate y
multiply (1)by 5.50
Multiply (2) by 1
5.50 x -5.50 y = 82.50
4.00 5.50 y = 440.00
Add the two equations
9.50 x = 522.50
/ 9.50
x = 55.00
plug value of x in (1)
x + - y = 15
55 + - y = 15
- y = -40
y= 40
55 Advance tickets
40 at the door tickets
