~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{P[old]/P[new]}}} = {{{10/11}}}   --->

{{{P[new]}}} = {{{(11/10)*P[old]}}}.         (1)

{{{P[new] - P[old]}}} = 600           (2)

Substitute (1) into (2) replacing {{{P[new]}}}. You will get

{{{(11/10)*P[old] - P[old]}}} = 600  --->

{{{(1/10)*P[old]}}} = 600  ---

{{{P[old]}}} = 6000   --->  {{{P[new]}}} = {{{(11/10)*6000}}} = 6600.
