Change in customers: 4838 - 4100 = 738\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide difference by the original: 738/4100 = 0.18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply by 100: 0.18*100 = 18%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The percent increase is 18%
\n" ); document.write( "
\n" );
