\n" ); document.write( "d = 2n
\n" ); document.write( "q = 2d
\n" ); document.write( "--------
\n" ); document.write( "Substitute for \"n\" and \"q\" and solve for \"d\"::
\n" ); document.write( "5(d/2) + 10d + 25(2d) = 1000
\n" ); document.write( "5d + 20d + 100d = 2000
\n" ); document.write( "125d = 2000
