    please help percentages

    Been struggling with this question an I would appreciate it if someone could please explain how to work it out.

    After a reduction of 9% in the original price, a car is sold for 8000. Both these values are correct to one significant figure.
    Calculate the greatest possible original price before the reduction was applied.

    Please can someone help me with this?
    I thank anyone one who does in advance.

    Hedgehog (:

    let x be the original price of the car so,

    x - (9/100)x = 8000, solve this equation for x.
