Today, everything at a store is on sale. The store offers a 20% discount.
If the regular price of an item is x dollars, what is the discount price in x dollars?
The discount price can be calculated by subtracting the discount amount from the regular price. The discount amount is 20% of x dollars, which can be expressed as 0.20x.
Therefore, the discount price in x dollars is x - 0.20x = 0.80x dollars.
