    Find 30% of the item and then subtract from the original value.

    Find 70% of the item and that is your answer.

    Answer:

    multiply the original price by the decimal of 30% then x 100  Lets say the item was £10 original price = 0.30 / £10  = 0.3 x 100 =£3  Then £3 is the discount of £10=£7    The second way is easier for smaller numbers 10% of £10 = 1 and then 1 x 3 =3  =£3 discount = £7 new price.
