ANSWER

$30.19

Step-by-step explanation

We want to find the total cost of the rug and floor mat (including taxes).

To do this, we first find the sum of the costs of both items:

24.81 + 3.94 = $28.75

Now, we have to find the tax. The tax is at 5%, which means we have to find 5% of the cost and then add it to the cost.

The tax (5%) is therefore:


\begin{gathered} (5)/(100)\cdot28.75 \\ =\text{ \$1.44} \end{gathered}

Now, we add that to the cost:


\begin{gathered} \text{ \$28.75 + \$1.44} \\ \text{ \$}30.19 \end{gathered}

That is the total cost.
