The spring concert at a certain high school sold 172 tickets. Students were charged ​$2 each and adults ​$6 each. The income from the sale of tickets was ​$724.

Question

Please help!

Answer 1

I suppose you want to find how many adult and student tickets were sold.

 

a = number of adult tickets at $6 each

172 - a = number of student tickets at $2

 

($6)a + ($2)(172 - a) = $724

 

6a + 2(172 - a) = 724

 

Now solve for a, then get 172 - a, and finish the solution.
