Question

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

Answer 1

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".

Answer 2

20% off the $40 dollar jacket.
