1 Si los sumandos son del mismo signo, se suman los valores absolutos y al resultado se le pone el signo común. 2 Si los sumandos son de distinto signo, se restan los valores absolutos (al mayor le restamos el menor) y al resultado se le pone el signo del número de mayor valor absoluto.
        
                    
             
        
        
        
Answer:
Step-by-step explanation: 
Group like terms 6y-2y= 2-1-2
When a number goes over the equal sign= positive + changes to negative, vice versa.
So final answer is 4y= -1= -4y
Because 4 is decided by -1
 
        
                    
             
        
        
        
The total cost is $41.85 
Amount Saved = 45 x 7 / 100
Amount Saved = 315 / 100
Amount Saved = $3.15 (answer).
In other words, a 7% discount for a item with original price of $45 is equal to $3.15 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.
