Answers

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 studenttickets.

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.

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
