An item that costs $30, when discounted 30 percent, will cost $21

The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 30 then divide it by 100.

To calculate percent off use the following equations:

(1) Amount Saved = Original Price x Discount % / 100
(2) Sale Price = Original Price – Amount Saved

Here are the solutions to the questions stated above:

1) What is 30 percent (%) off $30?

Using the formula one and replacing the given values:

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

Amount Saved = 30 x 30 / 100

Amount Saved = 900 / 100

Amount Saved = $9 (answer)

In other words, a 30% discount for an item with original price of $30 is equal to $9 (Amount Saved).

        2) How much to pay for an item of $30 when discounted 30 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 = 30 – 9

Sale Price = $21 (answer)

This means, the cost of the item to you is $21.

You will pay $21 for an item with original price of $30 when discounted 30%. In other words, if you buy an item at $30 with 30% discounts, you pay $30 – 9 = $21.
