A product originally costs \(\$125\). If the product goes on sale for 20% off, and then goes on sale for an additional 30% off, what is the price of the product?
You need to apply the discounts successively not just add the discounts. So price after original 20% discount is \(\$125 \times 80\% = \$100\). And is the price after the 2nd 30% discount.
