Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.
        
                    
             
        
        
        
Answer:
We end up with our original number
Step-by-step explanation:
Let x be our number
We increase by 100
increase = old number * 100%
increase = x*1
increase = x
New number = old number + increase
                        = x+x
                          =2x
Now we decrease by 50%
decrease = number *50%
                 = 2x*.5
                 =x
Final number = new number - decrease
                        = 2x-x
                          =x
