Markup means they sell it for that percentage more than they bought it for. First let's calculate how much they will mark it up for:
Convert 87% into a decimal(87/100):
Multiply:
This is how much they'll mark it up, now let's add it to how much they bought it for to find out the selling price:

Answer:
15 inches
Step-by-step explanation:
We assume that the edge of the small square is x (inches).
As the edge of the larger square is 2 inches greater than that of the smaller one, so that the edge of the larger square = edge of the small square + 2 = x + 2 (inches)
The equation to calculate the are of a square is: <em>Area = Edge^2 </em>
So that:
+) The area of the larger square is: <em>Area large square = </em><em> (square inches)</em>
+) The area of the smaller square is: <em>Area small square = </em><em>(square inches)</em>
<em />
As difference in area of both squares are 64 square inches, so that we have:
<em>Area large square - Area small square = 64 (square inches)</em>
<em>=> </em><em />
<em>=> </em><em />
<em>=> 4x + 4 = 64</em>
<em>=> 4x = 64 - 4 = 60 </em>
<em>=> x = 60/4 = 15 (inches)</em>
So the length of an edge of the smaller square is 15 inches
