In a room, all except
\n" ); document.write( " 18 of the people are over 50 years of
\n" ); document.write( " age. 15 of the people in the room are
\n" ); document.write( " under 50 years of age, if 10% of the
\n" ); document.write( " people are at the age of 50 years,
\n" ); document.write( " how many people are in the room?
\n" ); document.write( "-----
\n" ); document.write( "# over 50 = x -18
\n" ); document.write( "# under 50 = 15
\n" ); document.write( "# at 50 = 0.10x
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "x -18 + 15 + 0.10x = x
\n" ); document.write( "1.1x - 3 = x
\n" ); document.write( "0.1x = 3
\n" ); document.write( "x = 30 (# of people in the room)
\n" ); document.write( "----
\n" ); document.write( "Note:: the answer should be a whole number.
