Three species of bacteria are fed three foods: l, Il, and Ill. A bacterium of the first species consumes 1.3 units of food l, 1.3 units of food Il, and 2.3 units of food Ill each day. A bacterium of the second species consumes 1.1 units of food l, 2.4 units of food Il, and 3.7 units of food Ill each day. A bacterium of the third species consumes 6.9 units of l, 2.9 units of Il, and 5.1 units of Ill each day If 16,000 units of l, 28,000 units of Il, and 44,000 units of Ill are supplied each day, how many of each species can be maintained in this environment?
