Step-by-step explanation:
1) First, before getting started, let's assume the price of the product is  . This variable will be used a lot throughout the problem (
. This variable will be used a lot throughout the problem ( ).
). 
2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by  percent, the new price would be
 percent, the new price would be  .
. 
---> In this case, the price increased by  percent.
 percent. 
This means that it would be: 
New price is: 
3) The shopkeeper is then offering a  percent discount off of this marked price. When offering a
 percent discount off of this marked price. When offering a  percent discount price, the new price (with discount), expressed algebraically is:
 percent discount price, the new price (with discount), expressed algebraically is: 
---> the expression above simplifies to 
In this case,  ,
, 
---> 
This means that  , with discount, has been raised
, with discount, has been raised  .
. 
10.5 % is the profit percent 
(The profit percent being the final marked up price - purchased price)
 
        
             
        
        
        
[(upper legth + lower length) x height] divided by 2
        
             
        
        
        
What you do is you distribute the 5.
So your answer would be 5x+15
        
                    
             
        
        
        
Answer:
x= (y-5)/2
Step-by-step explanation:
Isolate the x variable.
y= 2x +5
Subtract 5 from both sides.
y-5=2x
Divide both sides by 2.
(y-5)/2= x
