Question 943287
Say the original price was {{{ p }}}
This price gets reduced by 30%
{{{ p - .3p = .7p }}} is the 1st reduced price
-------------------
This price gets reduced by 20%
{{{ .7p - .2*.7p = .7p*( 1 - .2 ) }}}
{{{ .7p*.8 = .56p }}}
------------------
The final price is {{{ .56p }}} which means
the reduction from the original price
was {{{ p - .56p = .44p }}}
44% reduction
----------------
If {{{ p = 578 }}}, then {{{ .44*578 = 254.32 }}}
$254.32 was taken off the original price
