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.
