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(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{\$}(21.5)/(yd^2)\cdot(1yd^2)/(9ft^2)=\text{\$}(2.39)/(ft^2)`

then, multiply by the area

`375ft^2\cdot(2.39)/(1ft^2)=\text{\$}896.25`

The cost for the cheaper carpet is $896.25
