Answer:
19 
Step-by-step explanation:
X will refer to the number. 
X+57( the number added to the original.)=4x. (x time 4) 
X+57=4x. 
Subtract x from both sides to get the variable on one side. 
(X+57)-x =(4x)-x
57=3x. You would then divide by 3 on both sides to again get integer isolated. 
57/3=3/3x. 
57/3=19. 3/3=1. 
19=x.
 
        
             
        
        
        
125 because it’s symmetrical between both
        
                    
             
        
        
        
Answer:
A: CxB= Total
A: (4x19)x5+25=$405
Step-by-step explanation:
First you would find the total of all of the 4 bags. Witch would be 4x19=76. Then you would multiply that by shipping cost 76x5=380. Lastly you would add the $25 380+$25= 405. Think that is right. Hope this helps!
 
        
             
        
        
        
Answer:
These correspond to two types of cost: fixed cost and variable cost. Fixed cost (FC): the cost of all fixed inputs in a production process. Another way of saying this: production costs that do not change with the quantity of output produced. Variable cost (VC): the cost of all variable inputs in a production process.
