This is the concept of simultaneous equations; We are required to create the equations modelling the above information.
Suppose the number of movie tickets was x and the number of meal tickets was y.
Therefore;
Total number of tickets was:
x+y=22
Total amount earned was:
0.5x+2y=25
The simultaneous equations representing the information is:
x+y=22
0.5x+2y=25
        
             
        
        
        
Answer:
30 or younger
Step-by-step explanation:
 
        
             
        
        
        
I believe that the answer is 22x
        
             
        
        
        
so x=5
substituting for x in the equation we get:
