Question

A department store is having a sale of 20% off of all kitchen appliances what is the sale price for a $250 microwave?

Answer 1

Answer:

300 dollars

Step-by-step explanation:

250 x 0.2= 50

250 + 50=300

Answer 2

so the sale price is 20% off the regular price, since 20% + 80% = 100%, the sale price will be 80% of the regular price.

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{80\% of 250}}{\left( \cfrac{80}{100} \right)250}\implies 200$
