To solve the exercise you can use a rule of three, like this
[tex]\begin{gathered} 25\text{\% }\rightarrow\text{ \$}8\Rightarrow\text{ Discount} \\ 100\text{\% }\rightarrow\text{ \$x }\Rightarrow\text{ Original price} \end{gathered}[/tex][tex]\begin{gathered} x=\frac{100\text{\%}\cdot\text{ \$8}}{25\text{\%}} \\ x=\frac{100\cdot\text{ \$8}}{25} \\ x=\text{ \$}\frac{100\cdot8}{25} \\ x=\text{ \$}\frac{800}{25} \\ x=\text{ \$}32 \end{gathered}[/tex]Therefore, the original price of the shoes was $32.00.
