1 answer:
Using x as the number of adult tickets sold
If 3x as many student tickets were sold as adults
--> the number of student tickets is 3x
If the total tickets is 572 and made up of 3x and x
This equation represents the relation ship
Total = 572
number of adult tickets + number of student tickets = 572
x + 3x = 572
When solving for x, we will find the number of adult tickets
x+3x =572
4x=572
x= 572/4
x= 143
143 adult tickets were sold
