\n" );
document.write( "Hi
\n" );
document.write( "Question states:
\n" );
document.write( "selling price of 60 of a certain stereo = 150*60 = $9000
\n" );
document.write( "The total cost of making 60 stereos = 90*60-0.02(60)^2 = 5400 - 72 = $5328\r
\n" );
document.write( "\n" );
document.write( "Percent markup is ($9000-$5328)/$5328 * 100 = 68.9 % \n" );
document.write( "
