325 adults and 612 children

A total of 937 people attended the play.  Admission was $2.00 for adults and $0.75  for students. The total ticket sales  amounted to $1,109. How many students  and adults attended the school play?  First complete the equations below, where A  stands for Adults and S stands for Students.

[325]A + [612]S = 1,109; A + S = [2.75]

325 (amount of adults)  x 2 (2 is the amount of money for each adult ticket)

= $650

937 (amount of people total in the play) - 325 (adults)

= 612 (kids)

612 x 0.75 (amount for each child)

= $459

$459 + 650 = $1109

325 + 612 = 937

its a straight line parallel to the time axis

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
