At the local nursery school, I was chatting to my daughter's friends and noticed a number of things.

Frankie has mousy coloured hair and the girl with black hair was wearing a green t-shirt.
Lucy is not blonde and Lauren does not have brown hair, Chloe was wearing a blue t-shirt.
The blonde girl was not wearing red and Lauren was not wearing green.
I can't remember who was wearing a yellow t-shirt.
Can you work out the colours of the t-shirt and hair for each child?

The local CD shop operates an unusual discount policy. The discount on the next purchase is worked out on the current purchase in the following way: for every whole pound spent you get 0.5% discount on the next purchase. For example, if you purchased £8.99 on the first purchase, you would then get a 4% discount on the next purchase and so on. You can make as many purchases as necessary.

You need to buy 7 CDs, costing, £11.50, £12.00, £12.00, £12.50, £13.00, £13.00 and £14.50. What is the cheapest method of buying them?
