Answer:
$5,760
Explanation:
Start by converting 20% to a decimal, by dividing by 100 = 0.20
Then, multiply 9,000 x 0.20 = 1,800 to get the amount taken off by the sale.
9,000 - 1,800 = 7,200, the first sale price.
Multiply 7,200 by 0.20 = 1,440 to get the amount of the second discount.
7,200 - 1,440 = $5,760, the final price of the car.
