Answer 1

To find the percent of the tip, we need to calculate the difference between the total price and the original price, and then divide that by the original price.

The difference between the total price ($16.20) and the original price ($13.50) is $16.20 - $13.50 = $2.70.

Now, we divide $2.70 by the original price ($13.50) and multiply by 100 to get the percent.

($2.70 / $13.50) * 100 = 0.2 * 100 = 20

So, the percent of the tip is 20%.

The correct answer is:

C) 20%
