					                   So first you will need to multiply 9 by 4. You get 36. Now you need to add the 10 percent and you get 39.6! That's the answer!
					                
					                
					             
					                   $9*4 sisters=$36 before discount 
+10% discount
10% = 3.6
36+3.6= 39.6
Price before discount =$39.60
					                
					             +10% discount
10% = 3.6
36+3.6= 39.6
Price before discount =$39.60
