Question

\How much would FRCC have to spend to cover the floor of a 25 ft by 35 ft classroom with stick-on carpeting that comes in packages that cover 15 square feet and cost $10.95 each?

Answer 1

Solution:

Gien:

$\begin{gathered} Floor\text{ of dimension }25ft\text{ by }35ft \\ 15ft^2\text{ }Carpet\text{ that costs \ 10.95} \end{gathered}$

The area of the classroom floor is;

$\begin{gathered} A=25\times35 \\ A=875ft^2 \end{gathered}$

To get te cost that will cover the floor,

$\begin{gathered} 15ft^2=\text{ \ 10.95} \\ 875ft^2=x \\ Cross\text{ multiplying,} \\ 15x=875\times10.95 \\ x=\frac{875\times10.95}{15} \\ x=\text{ \ }638.75 \end{gathered}$

Therefore, it will cost $638.75 to cover a classroom floor of 25ft by 35ft.
