You can  put this solution on YOUR website! You are going to make an equation that goes like this: 
11x+4y=154,000
 
But you also need a scond equation and that will be: 
x+y=28,000 ------> y=-x+28,000
 
Now, you will put it in the first equation like this: 
11x+4(-x+28,000)=154,000 
11x-4x+112,000=154,000 
7x+112,000=154,000 
  -112,000 -112,000 
7x=42,000 
__  ____ 
7    7 
x=6,000 tickets sold at $11
 
 
Now, you will find out how many for $4
 
11(6,000)+4y=154,000 
66,000+4y=154,000 
-66,000    -66,000 
4y=88,000 
__  _____ 
4     4 
y= 22,000 tickets sols at $4
