Question 1063847
60% decrease:
{{{ 11000 - .6*11000 = .4*11000 }}}
{{{ .4*11000 = 4400 }}}
--------------------------
70% increase:
{{{ 1.7*4400 = 7480 }}}
----------------------
{{{ (  7480 / 11000 )*100 = 68 }}}
{{{ 100 - 68 = 32 }}}
This is a 32% decrease
==========================
check:
Suppose you start with {{{ x }}} dollars
{{{ x*( 1 - .6 ) = .4x }}}
and
{{{ .4x*( 1 + .7 ) = .68x }}}
You end up with 68% of x. That is 
a 32% decrease in x
OK
