In Gotham City, the departments of Administration (A), Health (H), and Transportation (T) are interdependent. For every dollar's worth of services they produce, each department uses a certain amount of the services produced by the other departments and itself, as shown in Table 2.10. Suppose that, during the year, other city departments require $1 million in Administrative services, $1.2 million in Health services, and $0.8 million in Transportation services. What does the annual dollar value of the services produced by each department need to be in order to meet the demands?
