Answer:
The answer to your question is 3 tickets for students and 5 tickets for adults
Step-by-step explanation:
Data
Adults = a = $7.25
Students = s = $5.50
total tickets = 8
total cost = $52.75
Process
1.- Write equations for the problem
a + s = 8 --------------- l
7.25a + 5.50s = 52.75 --------------- ll
2.- Solve equation l for a
a = 8 - s
3.- Solve equation by substitution
7.25(8 - s) + 5.50s = 52.75
58 - 7.25s + 5.50s = 52.75
- 1.75s = 52.75 - 58
- 1.75s = - 5.25
s = -5.25/-1.75
s = 3
4.- Find a
a = 8 - 3
a = 5
5.- Result
3 tickets for students and 5 tickets for adults
