A theater will sell 500 tickets to a play. Adult tickets cost $10 per ticket and children tickets cost $7 per ticket. 
If they sold $3,860 in tickets, what system of equation will that represent.

<pre>
    x +  y =  500     (total tickets)

  10x + 7y = 3860     (total money),


where x is the number of adult tickets, y is the number of children tickets.
