Solve the problem.A certain area of forest is populated by two species of animals, which scientists refer to as A and B for simplicity. The forest supplies two kinds of food, referred to as F1 and F2. For one year, species A requires 1.3 units of F1 and 1.1 units of F2. Species B requires 2.4 units of F1 and 1.7 units of F2. The forest can normally supply at most 987 units of F1 and 478 units of F2 per year. What is the maximum total number of these animals that the forest can support?
