You have the following information:
- Total tickets sold = 282
- Number of student tickets sold = two times the adult tickets sold
In order to determine how many adult tickets were sold, you name x as the number of student tickets sold. Then, the number of adult tickets sold is 2x.
The sum of adult and student tickets sold was 282, then, you can write algebraically:
x + 2x = 282
you solve the previous equation for x, just as follow:
x + 2x = 282 simplify similar terms
3x = 282 divide between 3 both sides of the equation
x = 282/3
x = 94
Hence, the number of adult tickets sold was 94
