The total cost = $48,000
\n" ); document.write( "If three people cost $48,000 then the average cost is $16,000
\n" ); document.write( "Adding a fourth person, gives us $12,000
\n" ); document.write( "The difference is $4,000
\n" ); document.write( "--
\n" ); document.write( "The key here was least common multiple of 3 and 4 = 12. SO I knew the total cost was a multiple of $12,000.
\n" ); document.write( "
\n" );
