So I believe you will have to do 10% x 7 as it has been seven years which will be 70% and 70% of 8000 is 5600 so the answer will be £5600
        
             
        
        
        
c.y+3=f(x) and 0+3 therefore x=3
 
        
             
        
        
        
B. Y=2x
Which mean each 1 cost $2
If you buy 2 then it cost $4
I believe this is correct answer
        
                    
             
        
        
        
Given parameters: 
      y varies directly as w; 
    This interpreted implies that as y increases, we increases by a certain factor or amount; 
     So,  y ∝  w
            y  = kw
    where k is the constant of proportionality
Now, given that y  = 8 and w = 2
Input in the equation to solve for k; 
                8 = k x 2 
      Solving k gives, k = 4
Now to the second part, 
           if v is directly proportional to w; 
                 v  = k w
         So   v  = 4w
The equation that relates v to w is v = 4w
