Where is the maths in this? [WITMIT] : Lightbulbs

January 4, 2011

Two interesting photos of seemingly stupid pricing.

Sparks some thoughts about what is the worst deal I can get from this?
What happens if I want just one? Can I buy three and then give two back?

 Anyway, interested to hear your comments before I give some more thoughts and a possible explanation.

(Incidentally, the shops are The Range and Dunelms.)

    Love your ‘noticing’ here… there is so many rich seeds that can be used as a basis for mathematical thinking in the classroom out there. However, it is not always easy to see them.Do we do more maths than we think?

    Can’t help but wonder if this is anything to do with the fact that they’re energy saving bulbs.
