A store is having a 20% off sale on all merchandise if my buys one item and see if $13 what was the original price of a purchase

Answer :

Since all merchandise has 20% off, so the original price is multiplied by 0.8 (80%).

Let's use the variable x to represent the original price. So we can write the following equation and solve it for x:

[tex]\begin{gathered} 0.8\cdot x=13 \\ x=\frac{13}{0.8} \\ x=16.25 \end{gathered}[/tex]

Therefore the original price is $16.25.
