Answer to Problem 18STP

The cost for the carpet is $421.85. Hence, option D is correct

Explanation of Solution

Given information: The dimensions of rectangular bedroom are 13 feet by 11 feet. And, the cost of carpet per square feet is $2.95.

Calculation: Since, the dimensions of rectangular bedroom are 13feet by 11feet. Therefore, the area of rectangular bedroom is evaluated as,

  $\begin{array}{c}\text{Area of bedroom}=\left(13\right)\left(11\right)\\ =143{\text{ ft}}^2\end{array}$

Now, cost of 1 square feet of carpet is $2.95. Therefore cost of 143 square feet of carpet is evaluated as,

  $\begin{array}{c}{\text{Cost of 143 ft}}^2\text{carpet}=2.95\times 143\\ =\$421.85\end{array}$
