Before we begin to calculate percent off, let us ask ourselves, what is percent off? Percent off is the same as discount and it shows that the price of the product is reduced by a certain percent.

For instance, during Black Fridays most stores reduce the original prices of their products by a certain percentage or even when you have a percent off coupon which is the same concept.

A percent off of a product or service is a common discount format.

### Formula to Calculate Percent Off.

**Example 1:**

A supermarket put an offer of 5% off on a product that costs $200. Determine the percent off.

Thus, the percent off is $ 10.

**Example 2: **

Suppose you went shopping on a Black Friday and you decided to buy the following products since they were on offer.

Baby Diapers 48 pack@ $20 (15% off)

Blender@ $15 (7% off)

48 inches television@ $500 (35% off)

Calculate the amount of many that you saved for shopping on that weekend.

**Solution.**

The money saved is the percent off.

Therefore, let us begin with the baby diapers.

**Percent off = Original Price x Percentage off**

**= 20 x ^{15}/_{100}**

**= $3**

**Blender**

**= 15 x ^{ 7}/_{100}**

**= $1.05**

**Television.**

**= 500 x ^{35}/_{100}**

**= $175**

Hence, in total you saved $179.05 for shopping on Black Friday.
