If they reduced you 5% it means that you only paid 95% so 327.75 is equivalent to 95%
we multiply the initial value by 95% and obtain the price that was paid
[tex]x\times0.95=327.75[/tex]now solve x
[tex]\begin{gathered} x=\frac{327.75}{0.95} \\ \\ x=345 \end{gathered}[/tex]the price before the reduction was $345
