Answer:
To calculate the total amount of trash thrown away in the United States in 2013, you can multiply the average amount of trash thrown away per person per day by the number of people in the U.S. in 2013.
Trash per person per day = 4.5 × 10² grams
Number of people in the U.S. in 2013 = 3.2 × 10⁶ people
Now, calculate the total trash thrown away:
Total trash = (Trash per person per day) × (Number of people)
Total trash = (4.5 × 10² grams) × (3.2 × 10⁶ people)
Now, perform the multiplication:
Total trash = (4.5 × 3.2) × (10² × 10⁶) grams
Total trash = 14.4 × 10⁸ grams
To express this in standard notation, move the decimal point one place to the right:
Total trash = 1.44 × 10⁹ grams
So, about 1.44 × 10^9 grams (or 1.44 billion grams) of trash were thrown away in the United States in 2013.
