Finding Percentage Discount on a Jacket

A store is having a sale where all items are discounted by a certain percentage. If a jacket originally priced at $120 is sold for $90 during the sale, what percentage discount did the store apply to the jacket?

To find the percentage discount, use the formula:

$$ ext{Percentage Discount} = rac{ ext{Original Price} - ext{Sale Price}}{ ext{Original Price}} imes 100 $$
