You take 
7.25 (10)+5.5p=105.5
72.5+5.5p=105.5
To make the equation easier multiply the whole equation by ten like this
(72.5+5.5p=105.5)10 that equals
725+55p=1055
Then subtract 725 to both sides 
725+55p=1055
-725 -725
____ _____
 55p=330
Then divide by 55 on both sides and that equals 6 so 6 people bought tickets
        
                    
             
        
        
        
A relation is what it sounds like. A relation between numbers and/or objects.
A function is just a special type of relationship. In order for a relation to be a function, it must have only one output for one input.
On a graph, the x-axis is the input and the y-axis is the output. If you draw a vertical line through a point on the x-axis and there is only one point on that vertical line, then it is a function.
The only graph that meets these criteria is the first graph.
        
             
        
        
        
I think B is the answer. I am not sure
        
                    
             
        
        
        
It is 14 because 8= 6to-2 and 3to-3is 6 so both together is 14
hope this helps
