Answer: 146 Tickets
Step-by-step explanation:
So, we need to write an equation first to be able to solve this problem.
The variables we will be using are x, which represents how many adult tickets were sold.
Because we know that the student tickets sold were two times the adult, we can label the student tickets as 2x.
Our equation will be x + 2x = 438
Because x and 2x can be added together, it will make 3x.
3x = 438
x= 146
