Answer:
20%-X=a
Step-by-step explanation:
So if there is a toy that cost $50 and it was 20% off  it would then cost $40
 
        
             
        
        
        
The options you gave are extremely confusing, but if you round 7.9 it is 8, and if you round $3.89 it is $4. Therefore, the best estimate would be 8•$4, or $32
        
                    
             
        
        
        
The sum of y+x, or 5+7, is rational.  This is because each integer(non fraction/decimal)is rational, it is also rational.
