A Correct answer
Explanation

Successive discounts: 15000 * 0.8 * 0.9 * 0.9 = 15000 * 0.648 = 9720.

AI explanation

Using the successive discount formula, the final sale price equals the marked price multiplied by the remaining percentage factors. The calculation is 15000 * 0.80 * 0.90 * 0.90. This gives 15000 * 0.648 = 9720.
