Answer:
$41000
Step-by-step explanation:
If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year) 
0.1(x+1000)=4200 (divide 4200 by .01)
x+100=42000
42000-1000= 41000
 
        
                    
             
        
        
        
They are the same because they both have 4 sides
