Final answer:
The number of employed people in 2004 is calculated by subtracting the unemployed from the total labor force, resulting in 145 million employed individuals.
Step-by-step explanation:
To determine the number of employed people in 2004, we subtract the number of unemployed people from the total labor force. Given that the labor force consists of 150 million people and there are 5 million unemployed, we can calculate the number of employed individuals as follows:
Labor Force - Unemployed = Employed
150 million - 5 million = 145 million
Therefore, the correct answer is C. 145 million.
