\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "cocoa + cocoa = cocoa
\n" ); document.write( "0.55A + 0.25B = 0.48(A+B)
\n" ); document.write( "------------------------------
\n" ); document.write( "55A + 25B = 48A + 48B
\n" ); document.write( "7A = 23B
\n" ); document.write( "-----
\n" ); document.write( "One possible answer:
\n" ); document.write( "23 of the 55% bars
\n" ); document.write( "7 of the 25% bars
\n" ); document.write( "=======================
