Mandana is ordering new tile for her kitchen floor. the area of the floor is 117.7 square feet, and she wants to order between 15% and 20% extra of the materials. which of the following is a reasonable amount of tile for mandana to order?

To find a percentage increase of 15%, you can multiply the original value by 1.15.
To find a percentage increase of 20%, you can multiply the original value by 1.2.

117.7 * 1.15 = 135.355
So if she orders 15% extra tile, she will order around about 135.355 square feet.

117.2 * 1.2 = 141.24
And if she orders 20% extra tile, she will order around about 141.24 square feet.

Any number between those two values will be the amount of tile she might order.

A. is the answer in this question
