Answer:

The school sold 371 tickets for students and 566 tickets for non-students.

Explanation:

Let's say that the number of tickets sold to students is #x# and the number of tickets sold to non-students is #y#.

You know that the school sold a total of 937 tickets, which means that you can write

#x + y = 937#

You also know that the total sum collected from selling these tickets is equal to $3943, so you can write

#3 * x + 5 * y = 3943#

Use the first equation to write #x# as a function of #y#

#x = 937 - y#

Plug this into the second equation and solve for #y# to get

#3 * (937 - y) + 5y = 3943#

#2811 - 3y + 5y = 3943#

#2y = 1132 implies y = 1132/2 = color(green)("566 tickets")#

This means that #x# will be equal to

#x = 937 - 566 = color(green)("371 tickets")#

The school thus sold 371 tickets for students and 566 tickets for non-students.
