(a) Convert 10$\%$ to a fraction.
(b) Use your answer from (a) to estimate the sales tax Felipa would pay on a $\$ 95\$ dress.

A)
$$\begin{array}{l}{10 \%} \\ {=\frac{10}{100}}\end{array}$$
$$\begin{array}{l}{=\frac{\mathscr{10}^{\mathscr{}}}{\mathscr{10} \cdot 10}} \\ {=\frac{1}{10}}\end{array}$$
B)
$$\begin{array}{l}{\mathrm{a}=95 \cdot \frac{1}{10}} \\ {\mathrm{a}=(19 \cdot \not \vec{5}) \cdot \frac{1}{2 \cdot \mathscr{5}}}\end{array}$$
