To subtract a percentage from a price, convert the percentage into a decimal and multiply the decimal by the price. The answer is the amount to subtract from the original price.
Know MoreTo subtract 25 percent from a price of $20, first convert 25 percent into a decimal. The decimal form of 25 percent is .25, which represents 25 out of a total of 100. Next, multiply the decimal by the original price. Twenty multiplied by .25 equals 5. Thus, 25 percent of the $20 price is $5. Subtracting 25 percent of the price is the same as subtracting $5 from the price. In this example, an item that costs $20 with a 25 percent discount is sold for $15.
