Let x=total number of people in room, m=number of men, and w=number of women\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"80% of the occupants are women\", this means that \"w=0.8x\". Solving for \"x\" and we get \"w%2F0.8=x\" ----> \"x=1.25w\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also, we know that the number of men and women must total the number of people in the room. So this means that \"m%2Bw=x\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m%2Bw=x\" Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"35%2Bw=1.25w\" Plug in \"m=35\" (the number of men) and \"x=1.25w\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"35=1.25w-w\" Subtract w from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"35=0.25w\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"35%2F0.25=w\" Divide both sides by 0.25 to isolate \"w\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"140=w\" Divide\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is \"w=140\" which means that there are 140 women in the room
\n" ); document.write( "
\n" ); document.write( "
\n" );
