the cost is proportional to the number of people because a constant value 9.50 exists where each measure of the number of people multiplied by this constant gives the corresponding measure in y
        
             
        
        
        
A=4×-3 I think this is the equation
        
             
        
        
        
4+3 = 7
7^2 +6^2 
49+36 = 85
Radical85 = 9.21
So x will be 3.9
