At a store a hat has a regular price of x dollars. During a sale the price of the Harry U. S. Discounted by 20%. The expression 0.8x describes the discounted price in dollars of the hat. What expression also describe the discounted price in dollars of the hat

$x - $x/5

Step-by-step explanation:

Discount refers to reduction in the marked or regular price of an item. It is usually given in percentage (%).

In this question, Harry bought a hat marked for $x, and was given a discount of 20% on the hat. This means that 20% of the regular price ($x) was deducted for him.

Mathematically;

20% of $x = 20/100 × x

= 1/5 × x

= x/5

Hence, the discount price (amount deducted for Harry) is $x/5

Therefore, the amount payable by Harry for the hat (discounted price) is:

$x - $x/5

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.
