A total of 432 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Now, the number of adult tickets sold and student tickets sold added equal 432 tickets.
We also know that number of student tickets sold was three times the number of adult tickets sold. Therefore,
