Smart Cards have been growing in popularity in recent years. In 2006, 500 million Smart Cards are expected to be issued. This represents a 117% increase from the number of cards that were issued in 2001. How many Smart Cards were issued in 2001? Round to the nearest million.\r
\n" ); document.write( "\n" ); document.write( "If the number of cards issued went up by 117% then you have to multiply the 2001 number by 2.17 to get 500,000,000.\r
\n" ); document.write( "\n" ); document.write( "So, x*2.17=500000000 where x is the number we're trying to solve for.
\n" ); document.write( "Divide both sides by 2.17 and x=230,414,746.54377
\n" ); document.write( "That's 230,000,000 when you round to the nearest million. \n" ); document.write( "
\n" );
