Solution: The trick with this question is that typical population analysis isn’t enough. You must take into account residential use of plastic bags, as well as that of businesses, government employees, and so on until you can muster some convoluted quantity to appease your interviewer. Also consider bans on plastic bags, as found in cities like Los Angeles.

According to HowStuffWorks, 380 billion plastic bags are used in the US annually.
