A store is having a sale in which all items are 20% off. If p is the original price of an item, then the equation p - 0.2p = 0.8p can be used to find the sale price
find the sale price
We are given that there is a 20% sale in the store. Moreover, the sale price of an item is p - 0.2p, where p is the price of the item. So, we get that, p - 0.2p is equivalent to 0.8p
