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

and
![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.](https://tex.z-dn.net/?f=3x%2B4y%3D1740%5C%5C%5C%5C%5CRightarrow%203%28530-y%29%2B4y%3D1740~~~~~~~~~~~~~~~~~~~~~~%5B%5Ctextup%7BUsing%20equation%20%28i%29%7D%5D%5C%5C%5C%5C%5CRightarrow%201590-3y%2B4y%3D1740%5C%5C%5C%5C%5CRightarrow%20y%3D1740-1590%5C%5C%5C%5C%5CRightarrow%20y%3D150.)
From equation (i), we get

Thus, the required number of student tickets is 380 and adult tickets is 150.
