Thread: 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.

let x be the original price of the car so,

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