Hello! So, the price of the carton of paper is $27, and it may go on sale for 25% off. To find the sale price of the carton, all you have to do is multiply the price by the percentage. You get 25% off of the original price. However, you still have to pay 75% of it, because 25% is only the amount off and 100 - 25 is 75. Let's multiply. 27 * 75% (0.75) is 20.25. There. The sale price of the carton will be $20.25.
