Answer 1

$10^{^{\prime}}6^{\doubleprime}\text{ = 10' + (}\frac{6}{12})^{\prime}\text{ = 10.5'}$

Area of the wall = L x B = 10.5 ft x 14 ft =

$147ft^2$$\begin{gathered} total\text{ cost of the carpet before tax = 147 x \ 2.78 = \ 408.66} \\ S\text{ale tax of 7.5\% on the carpet = }\frac{7.5}{100}\text{ x \ 408.66} \\ =\text{ \ 30.6495} \\ \text{Total cost of the carpet = \ 408.66 + \ 30.6495} \\ =\text{ \ 439.2495} \\ \cong439.25\text{ (two decimal places)} \end{gathered}$
