Answer:
252 students
126 adults
Step-by-step explanation:
x= #student tickets
y= #adult tickets
x+y=378 x=2y
2y+y=378
3y=378
y=126
x=2(126)
x=252
ANSWER:
Total number of adult tickets sold were 126.
SOLUTION:
Given, a total of 378 tickets were sold for the school play. They were either adult tickets or student tickets.
The number of students tickets sold was two times the number of adult tickets.
We need to find how many adult tickets were sold?
Let, the number of student tickets be x.
And the number of adult tickets be y.
Then, total number of tickets are 378
x + y = 378 --- eqn (1)
And, no. of student tickets are two times the no. of adult tickets
No. of student tickets =2 x no. of adult tickets
x = 2y --- eqn (2)
Now, substitute the x value in (1)
2y + y = 378
3y = 378
y = 126
Hence, total number of adult tickets sold were 126
