Question 1186426
Step 1:
Price of ticket = $8 each.
Price of ticket after discount = 8 - 2 = $6

Total Price = $3580
Total Ticket = 525



Step 2:
Now, we have given

x represent the number of ticket sold at $8.
y the number of ticket sold at discount price.
Then, x + y = 525
8x + 6y = 3580

Therefore, 
System of equation is
x + y = 525
8x + 6y = 3580
