Answer:
ok let me try this again 
To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

Answer:
The length of the window is 35 inches.  
Step-by-step explanation:
Perimeter of an object can be found using the general formula:  P = 2W + 2L, where P = perimeter, W = width and L= length.  Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L':  112 = 2(21) + 2L, or 112 = 42 + 2L.  We can then use inverse (opposite) operations to isolate the variable and solve.  Whatever we do to one side of the equation, we do to the other.  We will start by subtracting 42 from each side:  112 - 42 = 42 - 42 + 2L or 70 = 2L.  Next, we divide both sides by 2 to solve for L:  70/2 = 2L/2 or L = 35.  So, the final length of the window is 35 inches.  
 
        
             
        
        
        
Answer:
11.2
Step-by-step explanation:
well i'm guessing that you didn't finish you parenthesis and if you did they would be around the 0 and 3 so 3 plus 0 is 3 and 3 plus 8.2 is 11.2 so I believe your answer is 11.2.  Sorry if it is wrong the question didn't really make sense.
