Answer: C
Step-by-step explanation:
They both end up equaling 4x+16 so they cancel each other out
 
        
             
        
        
        
It reveals the slope and a single point on the line
        
             
        
        
        
P(x) =9x +30 
the tips are a flat rate so it’s a constant 30 while the 9 per hour is dependent on the hours worked which is why it is attached to x as a coefficient
