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

Now, let's solve the questions stated above:

1) What is 45 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 45.


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

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

Amount Saved = 100 x 45 / 100
Amount Saved = 4500 / 100
Amount Saved = $45 (answer).

In other words, a 45% discount for a item with original price of $100 is equal to $45 (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 45 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 45 percent.

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

Sale Price = Original Price - Amount Saved. So,

Sale Price = 100 - 45

Sale Price = $55 (answer).

This means the cost of the item to you is $55.

You will pay $55 for a item with original price of $100 when discounted 45%.

In this example, if you buy an item at $100 with 45% discount, you will pay 100 - 45 = $55.

3) 45 is what percent off $100?

Using the formula (b) and replacing given values:

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

45 = 100 x Discount in Percent / 100
45 / 100 = Discount in Percent /100
100 x 45 / 100 = Discount in Percent
4500 / 100 = Discount in Percent, or

Discount in Percent = 45 (answer).
