    Q1 on paper was
    Is money discrete or continuous?
    I thought it could be both.

    I count my fortune every night so I would say discrete.

    Interesting. We deal potentially in discrete amounts of money, but in theory, money can be subdivided further and to whatever degree of accruacy you want
    BT Charge 2.024 pence per minute
    Petrol is priced at 136.9 pence per litre (interesting I have been told that the price is actually 136.9999999... however many 9's their till can cope with)
    Share prices and currencies are traded to many decimal places.

     
  5. Im not sure on the definition but I would hazard a guess that it only becomes discrete when you trying a physically realise it.

    I would agree depending on context it could be both.

    I agree. AQA require the answer discrete.
    No context given.
     
  9. I've always said "What you can count is Discrete, that which you measure is Continuous"
    Then there are shoe sizes, I know .......... 5½, 6, 6½ etc
