If a hat was originally priced at $35 and Paolo paid $28, what is the percentage discount?

To determine the percentage discount, you first need to calculate the amount of the discount. The original price of the hat is $35, and Paolo paid $28. The discount amount can be found by subtracting the price he paid from the original price:

Discount Amount = Original Price - Price Paid

Discount Amount = $35 - $28

Discount Amount = $7

Next, to find the percentage discount, you take the discount amount and divide it by the original price, and then multiply by 100 to convert it to a percentage:

Percentage Discount = (Discount Amount / Original Price) x 100

Percentage Discount = ($7 / $35) x 100

Percentage Discount = 0.2 x 100

Percentage Discount = 20%

Thus, the percentage discount that Paolo received on the hat is 20%. This calculation reflects how much less Paolo paid compared to the original price, expressed as a percentage of that original price.
