Answer:
$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
