Population puzzle

[Michael Doub]

I know that some of the folks on this list enjoy puzzles.   A friend sent me this one this afternoon and I thought it would be interesting to see the different approaches folks come up with and how fast it can be solved.   enjoy…

The 2010 Census puts populations of 26 largest US metro areas at 18897109, 12828837, 9461105, 6371773, 5965343,5946800, 5582170, 5564635, 5268860, 4552402, 4335391, 4296250, 4224851, 4192887, 3439809, 3279833, 3095313,2812896, 2783243, 2710489, 2543482, 2356285, 2226009, 2149127, 2142508, and 2134411.

Can you find a subset of these areas where a total of exactly 100,000,000 people live, assuming the census estimates are exactly right?
