The math behind plastic bottle recycling

Pencils

Ten Classrooms will receive a packet of pencils made from recycled newspapers.

It’s just one more week until Earth Day.  Here is an Earth Day Math problem submitted by one of our staff.  Don’t forget to send your Earth Day Math problems to earthday@ascendmath.com

The first 10 classrooms to send a math problem will get a  packet of pencils recycled from newspapers for their classroom.  It’s fun and there are many sources for Earth Day Facts.

Americans buy 29 billion bottles of water a year, more than any other nation.  It takes 17 million barrels of crude oil to make this many plastic water bottles.

How many billion bottles can be manufactured from one barrel of crude oil?

Extra Credit:  If Americans only bought 10 billion bottles next year how many barrels of oil would that take?
