Question 635356
A total of 925 tickets were sold for a game for a total of $2,495. if adult tickets sold for $5.00 and childrens sold for $2.00, how many of each kind of ticket were sold?
**
let x=no. of adult tickets sold
925-x=no. of children tickets sold
..
5x+2(925-x)=2495
5x+1850-2x=2495
3x=2495-1850=645
3x=645
x=215
925-x=710
..
no. of adult tickets sold=215
no. of children tickets sold=710
..
you could have continued with your solution by noting that: 
a+c=925
c=925-a
