Twice as many nickels as pennies:
\n" ); document.write( "n=2p
\n" ); document.write( "Four more dimes as nickels
\n" ); document.write( "d=n+4
\n" ); document.write( "as many quarters as dimes and nickles
\n" ); document.write( "q=d+n
\n" ); document.write( "Solve all for p
\n" ); document.write( "n=2p;p=1/2n
\n" ); document.write( "d=n+4;d=2p+4
\n" ); document.write( "q=(2p+4)+2p=4p+4..
\n" ); document.write( " \n" ); document.write( "
\n" );
