i believe the number is 72%.\r

\n" ); document.write( "\n" ); document.write( "take 72% and increase it by 25% of 72% and you get 72% + 18% = 90%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula would be 1.25 * x = 90%
\n" ); document.write( "divide both sides of this formula by 1.25 and you get:
\n" ); document.write( "x = 90% / 1.25 = 72%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
