Question 1129497

Use a system of linear equations with two variables and two equations to solve.

A concert manager counted 625 ticket receipts the day after a concert. The price for a student ticket was $12.50, and the price for an adult ticket was $17.00. The register confirms that $9,950.00 was taken in. How many student tickets and adult tickets were sold? 

I can solve the equation, but I just need someone to clearly explain how to equation should be set up in order to solve it? 
<pre>Let the number of students' and adults' tickets be S, and A, respectively
Then we get the following system: S + A = 625 -------- eq (i)
                              12.5S + 17A = 9,950 ---- eq (ii)
You said you can take care of it from here so go right ahead!
