a watch which normally sells for 259.95 is on sale for 15% off.
问题补充：However, if you buy the watch today, you will receive an additional 10% off of the sale price. What is the final sale price of the watch?
最佳回答：
原价 = 259.95
打折15%； 259.95 x 0.85 = 220.9575
再优惠10%； 220.9575 x 0.9 = 198.86175
手表最终售价 = 198.86175
