At a store, a hat has a regular price of x dollars. During sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars,
of the hat. Which expression also describes the discounted price, in dollars, of the hat?

x - 0.2x

Since the price of the hat is labelled = x,

The percentage discount on the hat price = 20%,

Thus, the discount = 20% of the price marked

= Twenty percent of x

=0.2 x =0.2 x

Therefore, the hat's new price = Marked price - Discount

= x- 0.2  = x
