At a store, a hat has a regular price of x dollars. during a sale, the price of that 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?

a) 0.2x
b) x - 20
c) x - 0.2
d) x - 0.2x

D) x - 0.2 x  also describes the discounted price, in dollars, of the hat.

Step-by-step explanation:

Since, the marked price of the hat = x,

The percentage discount on the price of the hat = 20 %,

Thus, the discount = 20 % of the marked price

= 20 % of x

= 0.2 x

Hence, the new price of the hat = Marked price - Discount

= x - 0.2 x

Which is the required expression which is equivalent to 0.8x.
