    Hi Mrs Binnie,
    The bread could have cost:
    £1, 50p, 20p, 10p, 5p, 1p = £1.86
    £2, 20p, 10p, 5p, 2p 1p = £2.38

    Most the bread could have cost = £2, £1, 50p, 20p, 10p, 5p
    = £3.85

    Challenge
    Add 9 + 6 first Add 7 + 6 first

    Add 8 + 6 first Add 8 + 5 first
    Least the bread could have cost = 50p, 20p, 10p 5p, 2p, 1p = 88p

      6 £2 coins which equals £12

      The least the bread could have cost would have been;

      6 1p coins which equals 6p
