Answer 1

`10^{^(\prime)}6^(\doubleprime)\text{ = 10' + (}(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 = }(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}`
