The cost of tires is $60.00 each with a 30% \r\n" );
document.write( "discount for 6 pairs or more. How much would \r\n" );
document.write( "it cost to replace the tires on 5 cars (not \r\n" );
document.write( "including spares)\r\n" );
document.write( "\r\n" );
document.write( "First multiply $60.00 by 12, because 6 pairs \r\n" );
document.write( "means 6×2 or 12 tires.\r\n" );
document.write( "\r\n" );
document.write( "             $60.00\r\n" );
document.write( "               × 12\r\n" );

document.write( ".30.  You can also drop the 0 on the end of\r\n" );
document.write( ".30 for multiplying, and just use .3 :\r\n" );
