Let $\$x$ be the price of the souvenir. Then the new price
Let $\$x$ be the price of the souvenir. Then the new price
$\begin{array}{cl}
= & x \times (1+70\%) \times (1-60\%) \\
= & \$ 0.68x
\end{array}$
Then, the percentage change in the price of the souvenir
$\begin{array}{cl}
= & \dfrac{0.68x – x}{x} \times 100\% \\
= & \dfrac{-0.32x}{x} \times 100\% \\
= & -0.32 \times 100\% \\
= & -32\%
\end{array}$
