    20%

    Step-by-step explanation:

    Initial price: £50

    Decreased price: £40

    The difference: £50-£40 = £10

    Percentage change: £10/£50*100% = 20 %

    So the formula for price change is amount of change / original price * 100

    50-40

    = 10

    10/50*100

    = 1/5*100

    = 20%
