Respuesta :
Students = 380
Adults = 150
You can get this by using x = students and y = adults. Then set up a cost equation of:
3x + 4y = 1740
and a total tickets equation of
x + y = 530
Solve using any method.

Answer: The required number of student tickets is 380 and adult tickets is 150.
Step-by-step explanation: Given that the talent show committee sold a total of 530 tickets in advance.
Student tickets cost $3 each and the adult tickets cost $4 each and the total made was $1740.
We are to find the number of student tickets and adult tickets that sold.
Let x and y represents the number of student tickets and adults tickets respectively that sold.
Then, according to the given information, we have
[tex]x+y=530\\\\\Rightarrow x=530-y~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
and
[tex]3x+4y=1740\\\\\Rightarrow 3(530-y)+4y=1740~~~~~~~~~~~~~~~~~~~~~~[\textup{Using equation (i)}]\\\\\Rightarrow 1590-3y+4y=1740\\\\\Rightarrow y=1740-1590\\\\\Rightarrow y=150.[/tex]
From equation (i), we get
[tex]x=530-y=530-150=380.[/tex]
Thus, the required number of student tickets is 380 and adult tickets is 150.
