B Correct answer
Explanation

The original price is \$585. After a 15% discount, the price is 585 * 0.85 = \$497.25. To reach $398, the additional discount is (497.25 - 398) / 497.25 = 99.25 / 497.25, which is approximately 0.1996 or 20%.

AI explanation

The price after the initial 15% discount is 85% of 585, which equals 497.25. The final price of the air conditioner is 398, meaning the additional discount amount is 497.25 minus 398, or 99.25. The additional discount percentage is 99.25 divided by 497.25 times 100, which is approximately 20%.
