You can put this solution on YOUR website!
tickets to the concert were $2.50 for adults and $1 for students. $1200 was collected and 750 tickets were sold. write a system of linear equations that can be used to find::
how many adults (a) and how many students (s) attended.
-----
Quantity:: a + s = 750 tickets
Value:::: 2.5a+s = 1200 dollars
------------------
Subtract and solve for "a":
1.5a = 450
---
a = 300 (# of adults attending)
---------
s = 750-300 = 450 (# of students attending)
----------
