    Well the answer is the amount of trash divided by the amount of people.

    First, you would convert the numbers to from Scientific notation. \[7.125 x 10^{10}\] would be 71,250,000,000 \[4.48 x 10^{6}\] would be 4,480,000

    Then you would divide the two new numbers, trash/people \[71,250,000,000\div4,480,000\]

    If this is hard to understand, then use easier numbers. For example If there are 20 bubbles in total and 4 bubble blowers, how many bubbles did each peson blow? Then, you might see the anser is oblviously 5. Correct? So, in your case, \[71,250,000,000\div4,480,000\] equals 15904.017851
