Let: x = cost of senior citizen ticket y = cost of student ticket
4x + 5y = 102 7x + 5y = 126
4x + 5y = 102 4x = 102 - 5y x = (102 - 5y)/4 x = 102/4 - 5y/4
7x + 5y = 126 7(102/4 - 5y/4) + 5y = 126 (714/4 - 35y/4) + 5y = 126 -35y/4 + 5y = 126 - 714/4
note: -35y/4 = -8.75y 714/4 = 178.5
-8.75y + 5y = 126 - 178.5 -3.75y = -52.5 y = -52.5/-3.75 y = 14
x = 102/4 - 5y/4 x = 102/4 - 5(14)/4 x = 8
x = cost of senior citizen ticket = $8/ea y = cost of student ticket = $14/ea
The price of senior citizen ticket is 8 and price of student ticket is 14.
What is Equation?
Two or more expressions with an Equal sign is called as Equation.
Let x be the price of senior citizen ticket
y be the price of student ticket.
On the **first day **of ticket sales the school sold 4 senior citizen tickets and 5 student tickets for a total of $102.
4x+5y=102..(1)
The school took in $126 on the **second day **by selling 7 senior citizen tickets and 5 student tickets .
7x+5y=126..(2)
Subtract equation 1 and 2
4x+5y-7x-5y=102-126
-3x=-24
Divide both sides by 3
x=8
Now let us find y
4(8)+5y=102
32+5y=102
Subtract 32 from both sides
5y=102-32
5y=70
y=14
Hence, the price of senior citizen ticket is 8 and price of student ticket is 14.

The price of each senior citizen ticket is $8, and the price of each student ticket is $14. This is derived from solving a system of equations based on ticket sales. The two equations were formed from the total sales on two different days.
