\"P%28x%29=R%28x%29-C%28x%29\"
\n" ); document.write( "\"P%28x%29=128x-%2876.5x%2B8755%29\"
\n" ); document.write( "\"P%28x%29=128x-76.5x%2B8755\"
\n" ); document.write( "\"P%28x%29=51.5x%2B8755\"
\n" ); document.write( ".

\n" ); document.write( "The breakeven point occurs when \"P%28x%29=0\"
\n" ); document.write( "\"+51.5x%2B8755=0\"
\n" ); document.write( "\"51.5x=-8755\"
\n" ); document.write( "\"x=-8755%2F51.5\"
\n" ); document.write( "\"x=-170\"
\n" ); document.write( "That number doesn't make sense.
\n" ); document.write( "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%3E0\".
