1256.64 is the area, because you use this equation- A=πr^2
#1 is x3
Bc x goes up 3 each time and y goes up 2 each time
Black Shoes:
Price = $79.45
Markup = 44% of 79.45 = 0.44 x 79.45 = $34.96
Price after Markup= $79.45 + $34.96 = $114.41
Brown Shoes:
Price = $133.99
Mark down = 21% of 133.99 = $28.14
Price after Mark down = $133.99 - $28.14 = $105.85
Difference in cost = $114.41 - $105.85 = $8.56
