The easiest way of calculating discount is, in this case, to multiply the normal price $100 by 15 then divide it by one hundred. So, the discount is equal to $15.
To calculate the sales price, simply deduct the discount of $15 from the original price $100 then get $85 as the sales price.
To calculate percent off use the following equations:
Here are the solutions to the questions stated above:
1) What is 15 percent (%) off $100?
Using the formula one and replacing the given values:
Amount Saved = Original Price x Discount % / 100. So,
Amount Saved = 100 x 15 / 100
Amount Saved = 1500 / 100
Amount Saved = $15 (answer)
In other words, a 15% discount for an item with original price of $100 is equal to $15 (Amount Saved).
2) How much to pay for an item of $100 when discounted 15 percent (%)? What is item’s sale price?
Using the formula two and replacing the given values:
Sale Price = Original Price – Amount Saved. So,
Sale Price = 100 – 15
Sale Price = $85 (answer)
This means, the cost of the item to you is $85. You will pay $85 for an item with original price of $100 when discounted 15%. In other words, if you buy an item at $100 with 15% discounts, you pay $100 – 15 = $85.
