Change in price = (new) - (old) = 19 - 25 = -6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide the change in price over the original price: -6/19 = -0.315789 (result is approximate)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now multiply by 100 to convert to a percentage: 100*(-0.315789) = -31.5789%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Percent Change = -31.5789% which is another way to say \"a decrease of 31.5789%\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------------------------------------\r
