\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Before they started, they had 156 times 125 daily rations.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "After n people left, they had (156 - n)(125 + 70) daily rations.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since they didn't change the amount of food they had, these two expressions must be equal.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Set them equal to each other and solve the resulting equation for n.
