Q:
\n" ); document.write( "The computer club bought a $300 computer, the members sharing the cost equally. If there had been 5 more members in the club each would have paid $5 less. How many members were in the club?
\n" ); document.write( "--------------------------------------------------
\n" ); document.write( "A:
\n" ); document.write( "Let x = number of members in the club
\n" ); document.write( " $\"300%2Fx+-+300%2F%28x+%2B+5%29\"$ = 5, multiply both sides by x(x + 5)
\n" ); document.write( " $\"300%28x+%2B+5%29+-+300x+\"$ = 5x(x + 5)
\n" ); document.write( " $\"5x%5E2+%2B+25x+-+1500\"$ , divide both sides by 5
\n" ); document.write( " $\"x%5E2+%2B+5x+-+300+=+0\"$
\n" ); document.write( "(x - 15)(x + 20) = 0
\n" ); document.write( "x - 15 = 0 OR x + 20 = 0
\n" ); document.write( "x = $\"highlight%2815%29\"$ , disregard x = -20
\n" ); document.write( "Number of members: $\"highlight%2815%29\"$ \n" ); document.write( "

\n" );
