OpenStudy (phi):

first, figure out the fraction: change in price divided by original price can you do that ?

OpenStudy (theedwardsfamily):

so...divide 475 to 275 right? and then multiply

jabez177 (jabez177):

Correct !

OpenStudy (theedwardsfamily):

Yay!

OpenStudy (theedwardsfamily):

i got $31

OpenStudy (phi):

try again, what is the difference between 475 and 275 ?

OpenStudy (perl):

$$ \large \frac{ (\text{ new price - original price })}{\text{original price}} \times 100 = \text{percent change} $$

OpenStudy (perl):

you should get a negative percent change because it is decreasing , but make it positive since you want the magnitude of it.
