However, they waste time fighting with the other group Problems members over the available food. There is some group size at which the net benefit is greatest because the animals spend least time on these unproductive activities, and thus can spend time on feeding, mating, etc. Assume that for a group of size x, the fraction of time spent scanning for predators is Problem 1 v S(a) = AT (ac + 1 ) Problem 2 v Problem 3 v and the fraction of time spent fighting with other animals over food is Problem 4 v F(x) = B(x + 1)2 Problem 5 v Problem 6 v where A, B are constants and A > 2B. Problem 7 v Find the size of the group for which the time wasted on scanning plus time wasted on fighting is smallest.
