Question 779520
Going up by 25% means the coat sold for
{{{ 300 + .25*300 }}}
{{{ 300*( 1 + .25 ) }}}
{{{ 1.25*300 = 375 }}}
------------------
25% off this price is:
{{{ 375 - .25*375 }}}
{{{ 375*( 1 - .25 ) }}}
{{{ .75*375 = 281.25 }}}
The final price is $281.25 
Gaining 25% and then losing 25%  did 
not result in going back to the
$300 original price
