Step-by-step explanation:

To solve this question, set two equations:

Let x be number of adults and y be number of students.

As there are in total 937 people, the equation would be the sum of both adults and children:

 ...... ( 1 )

As the total sale amount is $1109, the equation would be to add up the ticket fee:

 ...... ( 2 )

Put ( 1 ) into ( 2 ):

Put y into ( 1 ):

Therefore there are 612 adults and 361 students.
