Question

A suit is on sale for $154. If the original price of the suit was $440, what percent was discounted for the sale?

Answer 1

so, we know the original price is 440, but it got dropped to 154, for a difference of 286.

so, if we take 440 to be the 100%, what is 286 off of it in percentage anyway?


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 440&100\\ 286&p \end{array}\implies \cfrac{440}{286}=\cfrac{100}{p}\implies p=\cfrac{286\cdot 100}{440}`
