Adult tickets for the school musical sold for $3.50 and student tickets sold for $2.50. 321 tickets were sold altogether for a total of $937.50 in ticket sales. How many student tickets were sold and how many adult tickets were sold?
Let adult tickets =A
Let student tickets =S

3.50A + 2.50S =937.50, solve for A, S
A =135 - adult tickets sold.
S =186 - student tickets sold.
