On World Maths Day

Using statistics about smoking cigarettes is a great way to engage students in a Maths lesson especially since "World Maths Day" and "No Smoking Day" collide on March 12.
  • If a pack of cigarettes cost $9, how much will a pack-a-day smoker save in one week by quitting? 
  • Today's cigarettes contain 4000 chemicals. In 1994 it was 599. How many more ingredients exist today?
  • It takes 3-9 months after a smoker quits for coughing and breathing problems to decline. What is the range and median of this time?
  • A pack-a-day smoker puts half the money he/she saves in a year on buying a car, how much money is that?
  • If 30% of the tar from cigarettes is exhaled from the body, how much tar is left in a smoker's lungs?
