Solution:
(a) Given that the tiles that Bruce used were each 1/4 of a square foot in area.
Where x is the number of tiles and y is the area covered. Thus;
[tex]y=\frac{1}{4}x[/tex]
(b) Given the table;
Since 6 tiles are used to cover 1 square feet. Thus;
[tex]y=\frac{1}{6}x[/tex]
(c)
(d) From the graph above, Bruce covers more area per tile because 1/4 is larger than 1/6.
