This is a SIMPLE math problem, and should be just that!!
\n" );
document.write( "Let the number of people at the banquet be N
\n" );
document.write( "Then cost to each would be: 
\n" );
document.write( "If there were 5 less people, then the count would be N - 5
\n" );
document.write( "We then get the following per person cost-equation: 
\n" );
document.write( "150(N - 5) = 150N + N(N - 5) ------- Multiplying by LCD, N(N - 5)
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "(N - 30)(N + 25) = 0
\n" );
document.write( "N, or number of people at the banquet =              OR                N = - 25 (ignore) \n" );
document.write( "

\n" );
