Melanie is tiling her shower with blue and white square tiles. She needs enough tiles to cover 72 square feet. Each tile is the same size. To get the look that she wants, Melanie will use x blue tiles and y white tiles per square foot. Write an expression in terms of x and y that represents the total number of tiles needed per square foot. Now write an expression in terms of x and y that represents the total number of tiles needed for 72 square feet. Use the Distributive Property to write an expression that is equivalent to the expression you wrote in part B. The expressions in parts B and C are equivalent. Explain what this means in terms of Melanie’s situation. I need this asap.;-;
