# A jacket that regularly cost $40 is on sale for$32 what is the percent decrease in the price of the jacket?

from 40 to 32, is just 8 bucks, so the jacket went from 40 to 8, so is discounted by 8 bucks. now, if we take 40 to be the 100%, how much is 8 off of it in percentage? $\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 40&100\\ 8&x \end{array}\implies \cfrac{40}{8}=\cfrac{100}{x}$ solve for "x".
