Concept explainers
Write a system of equations, and use the inverse of the coefficient matrix to solve each system of equations. (See Example 1.)
Bacteria Colonies Three species of bacteria are fed three foods: I, II, and III. A bacterium of the first species consumes 1.3 units each offoods I and II and 2.3 units of food III each day. A bacterium of thesecond species consumes 1.1 units of food I, 2.4 units of food II, and 3.7 units of food III each day. A bacterium of the third species consumes 8.1 units of I, 2.9 units of II, and 5.1 units of III each day. If16,000 units of I, 28,000 units of II, and 44,000 units of III are suppliedeach day, how many of each species can be maintained in thisenvironment?
