I'll show you two ways of doing this. In both ways, keep in mind that to find a percent of a number, just change the percent to a decimal (move the decimal point two places to the left) and multiply by the number. For example, to find 80% of 200, first change 80% into the decimal 0.8. Now multiply 0.8 * 200 = 160. 80% of 200 is 160.
Method 1: The original price of the item is $230. The discount is 25%. Let's find 25% of $230. 25% of $230 = 0.25 * $230 = $57.50 The discount amount is $57.50. Now we subtract the amount of the discount from the original cost. Sale price = $230 - $57.50 = $172.50
Method 2. The original price is $230. That means that $230 is 100% of the price since 100% of a thing means the entire thing. Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%. The sale price is 75% of the original price. Now we find 75% of $230. 75% of $230 = 0.75 * $230 = $172.50
As you can see, both methods give you the same answer.$172.50.
Explanation: To find the discounted price of an item, you multiply the original sell price of the item by a decimal version of the percentage. So in this case you would multiply .25 by 230 to get 57.5 or $57.50.
