Answer:

Bruce's function:

$\displaystyle y=\frac{1}{4}x$

Felicia's function:

$\displaystyle y=\frac{1}{9}x$

<em>Bruce's tiles cover more area</em>

Step-by-step explanation:

<u>Functions </u>

We need to compare the area covered by tile of both Bruce and Felicia. We are required to find the function y, the area covered by the number of tiles he used, x.

We know the tiles used by Bruce cover 1/4 of a square foot, this is written as:

$\displaystyle y=\frac{1}{4}x$

To find the function for Felicia, we must use the data provided in the table

For example,

For x=9 tiles, y=1 sq ft

For x=18 tiles, y=2 sq ft

If we set

$\displaystyle y=kx$
