Question

karen purchased a DVD player on sale. the original price was $179.30. the sale price was 159.92 what is the first step in finding the percent markdown? find the percent markdown.

Answer 1

well, let's do so and hmmm you decide which is the 1st step :)

so the DVD costs originally 179.30 but the store is selling it marked down by "x" percent, down to 159.92, hmmmm 179.30 - 159.92 = 19.38.

so if we take 179.30(source amount) to be the 100%, what is 19.38 off of it in percentage?

`\begin{array}{ccll} amount&\%\\ \cline{1-2} 179.30 & 100\\ 19.38& x \end{array} \implies \cfrac{179.30}{19.38}~~=~~\cfrac{100}{x} \\\\\\ 179.3x=1938\implies x=\cfrac{1938}{179.3}\implies x\approx 10.81`
