The given data in the problem above is 4.5 x 10-1 kg of trash per day being thrown by an average person and the number of people in the U.S. which is represented as 3.2 x 106. The problem wants to find out as to how many kilograms of trash was being thrown away in the United States using the data above.
First, let us simplify the data given, 4.5 x 10-1 kg is equal to 40.5 kg which means there is 40.5 kg of trash per day that was thrown by an average person.
Second, simplify this 3.2 x 106 people is equivalent to 339.2 people in the U.S.
Then, multiply 40.5 kg with 339.2 people in U. S. , the result is 13,737.6 kg.
Therefore, the total trash that is being thrown by average person in the U.S. last 2013 is 13, 737.6 kg.
