Question 623736
There are two relationships described.  <P>
#1...total tickets which is made up of student tickets (s) and non student tickets (n) totals 150. Set up an equationL  s+n=150.  Solve one in terms of the other:  s=150-n.<P>
#2  Student tickets are $5 so the total revenue from student tickets is 5s (5 dollars times the number (s) of student tickets.)  Total revenue from non student tickets (n) is 8n.  The total revenue was $930 so 5s + 8n = 930.<P>
Substitute the s in terms of n (s=150-n) into that second equation (5s + 8n =930)<P>
5(150-n) + 8n = 930 --> 750 -5n + 8n = 930 ---> 3n = 180 ---> n=60.<p>
s=150-n = 150-60 = 90.
