OA is E. Could is not be C gievn that we know the estimated minimum per caipta?

I agree entirely with atlantic here: the wording of the question is just bizarre. The question asks what the per capita income was; the data is about estimates. Were the estimates any good? Maybe they're way off. So the answer already must be E, because of the wording of the question.

Still, let's say the word 'estimate' is never used in the question. Instead, say it asks: Is the per capita income greater than $16,500?

1) There were at least 330,000 people.
2) The total amount of money earned by people in the region was at least $5.5 billion.

The answer is still E. Perhaps we have exactly 330,000 people, and they earned several trillion dollars combined- the per capita income could be very high, as high as you like. Or, perhaps they 'only' earned $5.5 billion, but perhaps there are 5.5 billion people in the region. Then the per capita income would be $1.
