Final answer:
The number of people counted as unemployed in the given economy with a population of 100 million is 52 million.
Step-by-step explanation:
To find the number of people counted as unemployed, we subtract the number of people with civilian jobs from the total population and then subtract those looking for jobs.
population - employed - looking for jobs = unemployed
Given that the population is 100 million, the number of people counted as unemployed is:
100 million - 40 million - 8 million = 52 million.
Therefore, the number of people counted as unemployed is 52 million.
