Question

A sign in a clothing store said, "All prices reduced 25% . Final prices marked on tags." DeLea found a sweatshirt that showed a price of $27 . What was the original price of the sweatshirt?

Answer 1

if $27 is the discounted price, that means $27 is really 100% - 25%, so 75%
so $27 is really just the 75% of the original price, so \(\large \begin{array}{ccllll}
quantity&percentage\\
\hline\\
x&100\\
27&75
\end{array}\implies \bf \cfrac{x}{27}=\cfrac{100}{75}\)
