Answer:
110
Step-by-step explanation:
4 x ( 3+ 52) ÷ 2
4 x 55 ÷ 2 
220 ÷ 2 = 110
 
        
                    
             
        
        
        
Answer:
The solution for y = -1.
Step-by-step explanation:
Given:
 ....(1)
    ....(1)
 ....(2)
  ....(2)
So, to solve for y, first we solve for x in equation (2):

⇒
Dividing both sides by 2,
⇒ 
            
Now, substituting the value of x  in equation (1):

⇒
⇒
⇒
⇒
⇒
Dividing both sides by 11,
⇒
Therefore, the solution for y = -1.
 
        
             
        
        
        
The total amount is "x", so, if 22.8 is 58%, "x" is the 100%,
 
 
        
        
        
It’s 225,000,000= 225 million
