In 2005, the total waste generated in a certain country was 7.125 x 10^10 pounds. Also in 2005, the countries population was 4.48 x 10^6 people. Determain the garbage per capita (per person) in that country in the year 2005.
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 \[71,250,000,000\div4,480,000\]
So the answer is 9207.58928571?
Whitch then if I round it it would be 9207.59?
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
Sorry I couldn't find my calculator :p
ok so it would be 15904.02? cause i have to round it?

grr it says its wrong! Is that in scientific notation?
You need and answer in scientific notation?
Well after you round it to 15904.02 it would be.... hold on one sec.
In scientific notation answer will be 1.590 x 10^4
The answer was 1.59 x 10^4 cool thanks!
Well sorry I didn't take you all the way there :( A special thanks to @ritez for helping me :D
