Question

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

Answer 1

The answer is D

Answer 2

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

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

`=(20* x)/(100)`

= 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.
