---------
{{{ x = 10 }}}
{{{ P(10) = 12*10 - 100 }}}
{{{ P(10) = 20 }}}
---------
{{{ x = 50 }}}
{{{ P(50) = 12*50 - 100 }}}
{{{ P(50) = 600 - 100 }}}
{{{ P(50) = 500 }}}
---------
{{{ x = 100 }}}
{{{ P(100) = 12*100 - 100 }}}
{{{ P(100) = 1200 - 100 }}}
{{{ P(100) = 1100 }}}
---------
{{{ x = 1000 }}}
{{{ P(1000) = 12*1000 - 100 }}}
{{{ P(1000) = 12000 - 100 }}}
{{{ P(1000) = 11900 }}}
--------
{{{ x = 2000 }}}
{{{ P(2000) = 12*2000 - 100 }}}
{{{P(2000) = 24000 - 100 }}}
{{{ P(2000) = 23900 }}}
