\n" );
document.write( "profit for producing and selling x units
\n" );
document.write( "P(x) = 2.25x - 7000
\n" );
document.write( "profit at 2000 Units
\n" );
document.write( "P(2000) = 2.25*2000 - 7000 = -$2500
\n" );
document.write( "profit at 5000 Units
\n" );
document.write( "P(5000) = 2.25*5000 - 7000 = $4250
\n" );
document.write( "break-even point for sales
\n" );
document.write( "0 = 2.25x - 7000
\n" );
document.write( "7000 = 2.25x
