•  
• Sale Price = Orig. Price - Amount Saved (b)

How to calculate Percent-off

Now, let's solve the questions stated above:

1) What is 10 percent off $100? Find the amount of discount.

Suppose you have a Kohls coupon of $100 and you want to know how much you will save for an item if the discount is 10 percent.

Solution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 100 x 10 / 100
Amount Saved = 1000 / 100
Amount Saved = $10 (answer).

In other words, a 10% discount for a item with original price of $100 is equal to $10 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.

2) How much to pay for an item of $100 when discounted 10 percent (%)? What is item's sale price?

Suppose you have a L.L. Bean coupon of $100 and you want to know the final or sale price if the discount is 10 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 100 - 10

Sale Price = $90 (answer).

This means the cost of the item to you is $90.

You will pay $90 for a item with original price of $100 when discounted 10%.

In this example, if you buy an item at $100 with 10% discount, you will pay 100 - 10 = 90 dollars.

3) 10 is what percent off 100 dollars?

Using the formula (b) and replacing given values:

Amount Saved = Original Price x Discount in Percent /100. So,

10 = 100 x Discount in Percent / 100
10 / 100 = Discount in Percent /100
100 x 10 / 100 = Discount in Percent
1000 / 100 = Discount in Percent, or

Discount in Percent = 10 (answer).
