Answer:
Number of children tickets = 400
Number of students tickets = 300
Number of adults tickets = 800
Step-by-step explanation:
Let the number of children tickets = 
Let the number of students tickets = 
Let the number of adults tickets = 
Total number of tickets sold = 1500
Writing the equation:
.... (1)
Price for each children ticket = $1.50
Price for each student ticket = $3
Price for each adult ticket = $5
Total money brought in = $5500
..... (2)
Number of student tickets sold was 100 lesser than number of children's tickets.
i.e.
..... (3)
Putting value of
from (3) in equation (1) and equation (2):


Multiplying equation (4) by 5 and subtracting equation (5) from it:

By equation (3):

By equation (1):

Therefore, the answer is:
<em>Number of children tickets = 400</em>
<em>Number of students tickets = 300</em>
<em>Number of adults tickets = 800</em>
