People in the United States throw away 2.5 million plastic bottles per hour. How many bottles per year are thrown away.
2.5 * 24 * 365 = ________ million
21,900,000,000 = 21 trillion, 909 million
To find out how many plastic bottles are thrown away per year in the United States, we can start by calculating the number of bottles thrown away per hour.
Given that 2.5 million plastic bottles are thrown away per hour, we need to multiply this number by the total number of hours in a year.
There are 24 hours in a day, so we multiply 2.5 million by 24 to get the number of bottles thrown away per day.
2.5 million x 24 = 60 million bottles per day.
Next, we need to calculate the number of days in a year. Commonly, we consider there to be 365 days in a year.
Now, to find the number of bottles thrown away per year, we multiply the number of bottles thrown away per day by the number of days in a year.
60 million x 365 = 21,900 million or 21.9 billion plastic bottles per year.
Therefore, people in the United States throw away approximately 21.9 billion plastic bottles per year.
