Question 990519
{{{P(x)=R(x)-C(x)}}}
{{{P(x)=128x-(76.5x+8755)}}}
{{{P(x)=128x-76.5x+8755}}}
{{{P(x)=51.5x+8755}}}
.
.
.
The breakeven point occurs when {{{P(x)=0}}}
{{{ 51.5x+8755=0}}}
{{{51.5x=-8755}}}
{{{x=-8755/51.5}}}
{{{x=-170}}}
That number doesn't make sense. 
Issue here is that even when you make 1 widget, you're already making profit since the revenue function is greater than cost function for all {{{x>0}}}.
