Question 1058748
Is {{{ P(5) - P(4) }}} positive or negative?
{{{ P(5) = 10*5^3 - 50*5^2 + 20*5 + 100000 }}}
{{{ P(5) = 1250 - 1250  + 100 + 100000 }}}
{{{ P(5) = 100100 }}}
--------------------------
{{{ P(4) = 10*4^3 - 50*4^2 + 20*4 + 100000 }}}
{{{ P(4)  = 640 - 800 + 80 + 100000 }}}
{{{ P(4) = -80 + 100000 }}}
{{{ P(4) = 99200 }}}
----------------------
{{{ 100100 - 99200 = 900 }}}
{{{ P(5) - P(4) }}} is positive, so profits
increased from 1994 to 1995
