Once you have the total force applied by the people on the raft as well as the net force created by each log (the difference between mg and the buoyant force), you need to find the number of logs that will make the force applied by the people + the net force of all the logs = 0 F(p) = force...

Find the force generated by the 4 people on the raft, as well as the net force per log. That should set you on the right course.
