Total Cost= Variable Cost - Fixed Cost\r
\n" ); document.write( "\n" ); document.write( "0 = $3x - 600 solve for x\r
\n" ); document.write( "\n" ); document.write( "600=3x
\n" ); document.write( "600/3=x
\n" ); document.write( "x=200 is the breaking point for the first question.\r
\n" ); document.write( "\n" ); document.write( "800=2x
\n" ); document.write( "800/2=x
\n" ); document.write( "x=400 is the breaking point for the second question.
