## How to work out discounts - Step by Step

To calculate discount it is ease by using the following equations:

• Amount Saved = Orig. Price x Discount % / 100 (a)
•
• Sale Price = Orig. Price - Amount Saved (b)

Now, let's solve the questions stated above:

### 1) What is 90 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 90.

Solution:

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

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

Amount Saved = 100 x 90 / 100
Amount Saved = 9000 / 100

In other words, a 90% discount for a item with original price of \$100 is equal to \$90 (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 90 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 90 percent.

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

Sale Price = Original Price - Amount Saved. So,

Sale Price = 100 - 90

This means the cost of the item to you is \$10.

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

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

### 3) 90 is what percent off \$100?

Using the formula (b) and replacing given values:

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

90 = 100 x Discount in Percent / 100
90 / 100 = Discount in Percent /100
100 x 90 / 100 = Discount in Percent
9000 / 100 = Discount in Percent, or

Discount in Percent = 90 (answer).
