You would first find the price of the car at the 30% discount.

30/100 * 18000 = 5400

Then subtract that value from the original price of the car.

18000 - 5400 = 12600.

Hence the price of the card is £12600 after the 30% discount.

To find r%:

9450/12600 x 100 = 75%

To check you answer

75/100 * 12600 = 9450
