The students at Maryville High School were challenged to join the Great American
Smokeout. One-fifth of the students signed
a pledge saying they would not smoke on
November 20. A third of the students
promised to talk to someone who smoked
about the dangers of smoking. The rest of
the students didn't participate. There are
one thousand, sixty-six students at MHS.
How many of the students didn't participate
in the Great American Smokeout?
