Question

Cammy bought a jacket at $43.50. The

price was 25% off the regular price.
What was the regular price?

Answer 1

well, the regular price was "x" and that's namely the 100%.

however today's price is 43.50, and we know that's 25% off the regular "x" price , hmmm so 100% - 25% = 75%, so 43.50 is really 75% of the regular price, so

`\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 43.50&75 \end{array}\implies \cfrac{x}{43.50}=\cfrac{100}{75}\implies \cfrac{x}{43.50}=\cfrac{4}{3} \\\\\\ 3x=174\implies x=\cfrac{174}{3}\implies x=58`
