725 tickets were sold for a game for a total of $1325 if adult tickets were sold for $2.50 and children's tickets sold for one dollar how many of each kind of ticket were sold
+36916 725 tix total
x = adult revenue from adult tix = $2.50 x
725-x = child revenue from child tix = $ 1.00 (725-x) revenues summed = $ 1325
2.50 x + 1.00 (725-x) = 1325 solve for 'x' the # adult tix.......then child tix = 725-x
