FAQs on Percent-off

What's 10 percent-off $500?

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

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

Amount Saved = 500 x 10 / 100

Amount Saved = 5000 / 100

Amount Saved = $50 (answer).

In other words, a 10% discount for an item with an original price of $500 is equal to $50 (Amount Saved).

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

What's the final price of an item of $500 when discounted $50?

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

Sale Price = Original Price - Amount Saved. So,

Sale Price = 500 - 50

Sale Price = $450 (answer).

This means the cost of the item to you is $450.

You will pay $450 for an item with an original price of $500 when discounted 10%.

In this example, if you buy an item at $500 with 10% discount, you will pay 500 - 50 = 450 dollars.

50 is what percent off 500 dollars?

Using the formula (b) and replacing given values:

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

50 = 500 x Discount in Percent / 100

50 / 500 = Discount in Percent /100

100 x 50 / 500 = Discount in Percent

5000 / 500 = Discount in Percent, or

Discount in Percent = 10 (answer).
