Answer 1

Start finding the area of the room

$15ft\cdot25ft=375ft^2$

then, using the cost per sq. ft, multiply them both and find the cost for carpeting the total area of the room in both situations.

for the first situation:

$375ft^2\cdot\frac{2.88}{1ft^2}=\text{\ }1080$

for the second situation:

convert the cost that is given in sq. yds to sq. ft using the conversion factors

$\text{\ }\frac{21.5}{yd^2}\cdot\frac{1yd^2}{9ft^2}=\text{\ }\frac{2.39}{ft^2}$

then, multiply by the area

$375ft^2\cdot\frac{2.39}{1ft^2}=\text{\ }896.25$

The cost for the cheaper carpet is $896.25
