Question 979467
Let {{{ p }}} = the original price
{{{ p + .3p = 1.3p }}} is the original price
with a 30% markup
-------------------
Now discount this price by 20%
{{{ 1.3p - .2*( 1.3p ) }}}
{{{ 1.3p - .26p = 1.04p }}}
-------------------------
This is the final price, an you are told
it is $450, so
{{{ 1.04p = 450 }}}
{{{ p = 450/1.04 }}}
{{{ p = 432.69 }}}
----------------
The original price should be $432.69
