\n" );
document.write( "1) Scientific Notaton is a 'shorthand' version expressing the number via a power of ten
\n" );
document.write( "$38,460,000, and the $27,980,000 is scientific notation
\n" );
document.write( "$38,460,000. = 3.846x10^7 (Note: deciamal point moved 7 units to left)
\n" );
document.write( "$27,980,000. = 2.798x10^7\r
\n" );
document.write( "\n" );
document.write( "Increase in sales from 2009 to 2010
\n" );
document.write( "3.846x10^7 -  2.798x10^7 = 1.048x10^7\r

document.write( " % of that increase of the 2009 sales
\n" );
document.write( "1.048x10^7/ 2.798x10^7 = .375 or 37.5% \n" );
