Let the cost of a senior ticket  = S

Let the cost of a child's tickets   = C

 

So

 

3S +  1C  =   38       (1)

3S +  2C   =  52       (2)

 

Subtract (1)  from (2)

 

C  =  14       this is  the cost of a child's ticket ( in dollars) 

 

Sub this  into  (1)

 

3S  + 1 (14)  = 38

3S  +  14   =  38       subtract 14 from both sides

3S   =  24                 divide both sides y 3

 

S  =   8        this is the cost of a senior ticket  (in dollars)
