Answer:

  3.65×10⁹ lbs/month, or 3.65 billion*

Step-by-step explanation:

[tex]\dfrac{6\,bags}{1\,household\cdot month}\cdot\dfrac{4\,lbs}{1\,bag}\cdot\dfrac{1\,household}{2\,people}\cdot\dfrac{3.04\cdot 10^8\,people}{1\,US}\\\\=\dfrac{6\cdot 4\cdot 3.04\cdot 10^8\,lbs}{2\,US\cdot month}\approx 3.65\cdot 10^9\,\text{lbs/month for US population}[/tex]

_____

10⁹ = 1 billion in "short scale" countries such as the US
