Answer:
The answer to your question is $21.0
Step-by-step explanation:
Data
Original price = $25
Discount = 20%
Taxes = 5%
Process
1.- Calculate the price with the discount
                      $25 ------------------- 100%
                         x   -------------------   20%
                         x = (20 x 25) / 100
                         x = 500 / 100
                         x = $5
Price after the discount = $25 - $5
                                        = $20
2.- Calculate the price after taxes
                      $20 ---------------------- 100%
                          x  -----------------------   5%
                        x = (5 x 20) / 100
                        x = 100 / 100
                        x = $1
Final price = $20 + $1
                  = $21   
 
        
             
        
        
        
Given:
y is directly proportional to x.
 when
 when 
To find:
The equation that connects y with x.
Solution:
It is given that, y is directly proportional to x. So,

 ...(i)
                     ...(i)
Where, k is the constant of proportionality.
We have,  when
 when  . Substituting these values in (i), we get
. Substituting these values in (i), we get
 
 
Divide both sides by 5.
 
 
 
 
Substituting  in (i), we get
 in (i), we get
 
  
Therefore, the required equation is  .
