Solve.
People in the United States throw away 2.5 million plastic bottles per hour. How many bottles per year are thrown away?
Blank Space__________billion bottles per year
To solve this, we need to find the number of bottles thrown away per hour and then multiply it by the number of hours in a year.
2.5 million plastic bottles per hour x 24 hours per day x 365 days per year = 21,900,000,000 bottles per year
Therefore, the blank space should be filled with 21.9 billion bottles per year.
