If the price of $39.60 corresponds to 45% of the original price, we can use the following rule of three to find the price that corresponds to 100% of the original price:
[tex]\begin{gathered} \text{price}\to percentage \\ 39.6\to45\% \\ x\to100\% \end{gathered}[/tex]Now, we can write the following proportion and solve it for x:
[tex]\begin{gathered} \frac{39.6}{x}=\frac{45}{100} \\ x\cdot45=39.6\cdot100 \\ x=\frac{39.6\cdot100}{45} \\ x=88 \end{gathered}[/tex]Therefore the original price was $88.
