x = number of adult tickets
y = number of student tickets
7.25x + 5.50y = 52.75
x + y = 8

x=8-y
7.25(8-y) + 5.50y = 52.75
7.25*8 - 7.25y + 5.50y = 52.75
58 - 1.75y = 52.75
5.25 = 1.75y
y = 3
x = 8 - 3 = 5

5 adult tickets, 3 student tickets

The number of adults tickets and student tickets purchased is 5 and 3.

Given that,

  • Tickets to a movie cost $7.25 for adults and $5.50 for students.
  • A group of friends purchased 8 tickets for $52.75.
  • Here we assume the no of adult tickets and no of student tickets be x and y.

Based on the above information, the calculation is as follows:

7.25x + 5.50y = 52.75 .............(i)

x + y = 8

x = 8 - y..................(2)

Now put the x value in the equation (1)

So,  

7.25(8-y) + 5.50y = 52.75

7.25 × 8 - 7.25y + 5.50y = 52.75

58 - 1.75y = 52.75

5.25 = 1.75y

y = 3

So,  

x = 8 - 3

= 5

Therefore we can conclude that the number of adults tickets and student tickets purchased is 5 and 3.
