Real Life Mathematics in Year 9

18 07 2012

I always manage to notice more examples of Mathematics in the newspapers over the holidays.

Last week I saw that the Toyota Prius averages 4.4L/100km and costs just under $36000. As a comparison the Holden Cruze averages 6.6L/100km and costs approximately $22000 for the base model. I asked Year 9 to work out how many kilometres a Prius needs to be driven for the petrol savings to equal the lower cost of the Cruze. Then we had a good discussion about being environmentally considerate.
