A discount of 20% on a $15 cap due to a logo error results in what selling price?

To determine the selling price after a 20% discount on a $15 cap, first, you need to calculate the amount of the discount. A 20% discount means you take 20% of the original price of $15.

Calculating 20% of $15 is done by multiplying $15 by 0.20, which gives you $3. This amount represents the discount off the original price.

Next, to find the selling price after applying the discount, you subtract the discount amount from the original price. So, you take the original price of $15 and subtract the $3 discount (which equals $15 - $3 = $12).

Thus, the final selling price of the cap, after applying the 20% discount due to the logo error, is $12. This confirms that the correct selling price is indeed $12.
