Write an article based on this "Write down the original price and the discount percentage. Find the opposite of the discount percentage. Convert the opposite percent into a decimal. Multiply the original price by the new decimal. Calculate your savings afterward to feel better."
The original price is usually the big number that retailers will mark through or make especially large so you know how good of a "deal" you're getting. Be sure to also pay attention to whether the discounted percentage applies to a single item or the total. This trick lets you perform 1 calculation instead of 2! The opposite of a percent is 100% minus the percent you are working with, i.e. the amount of the item you are still paying for. If you want to buy a shirt that is 30% off, the opposite of this is 70%, meaning you would have to pay 70% of the original price. To convert a percent into a decimal, divide by 100%, multiply times 0.01, or move the decimal two places to the left. In this example, 70%/100% = 70/100 = 7/10 = 0.7. If the shirt you want is $20, multiply $20 by 0.7. This comes to $14, meaning the shirt is now on sale for $14. Once you get home, it can be a good idea to check your receipts, not only to make sure the discounts were applied correctly but to see how much you saved altogether. Here, you can simply subtract the sale price from the original price ($20 - $14 = $6 saved)!
