115% of the price is 270,25
115*x/100=270,25
x=270,25*100/115
x=235  $ is the price
270,25-235= 35,25 $ is the tax
        
             
        
        
        
Answer:
C) 
Step-by-step explanation:
Use the Angle Addition Postulate to figure this out:

165° = (x + 15)° + (9x)°
 165° = (15 + 10x)°
-  15°   - 15°
_____________
