Calling our variables n and d we have
\n" ); document.write( "n = 2d and n = 12 + d
\n" ); document.write( "Since they are both equal to n, set them equal and get
\n" ); document.write( "2d = 12 + d
\n" ); document.write( "d = 12
\n" ); document.write( "n = 24
\n" ); document.write( "so that 12(.10) + 24(.05) = $2.40
\n" ); document.write( "
\n" );
