One solution is to guess at the answer, which is fairly easy since 150 isn't a huge number. 10*15 = 150, so 15 seats per row, 10 rows.\r

\n" ); document.write( "\n" ); document.write( "Or, you could let x = number of rows, x+5 = number of seats per row so that x(x+5) = 150, then solve the quadratic by rearranging and factoring, or by quadratic formula. \n" ); document.write( "
