old price = 2400
\n" ); document.write( "new price = 2040
\n" ); document.write( "difference = 2400 - 2040 = 360
\n" ); document.write( "difference divided by old price = 360 / 2400 = .15
\n" ); document.write( "that is the rate of the difference.
\n" ); document.write( "the percent of the difference is the rate of the difference * 100%
\n" ); document.write( "the percent of the difference = .15 * 100% = 15%
\n" ); document.write( "since the new price is less than the old price, that is the percent of the decrease.\r
