Question

A recent visit to the hair salon cost Brenda $130. She added a 15 percent tip to her bill. What is the amount of the tip?

Answer 1

19.5 is the amount of the tip

Answer 2

15% / 100 = 0.15. 15% = 0.15 in decimal form.
Now, all you need to do is multiply $130 by the decimal form of the percentage.
$130 * 0.15 = $19.50. Here tip was $19.50. Always remember that you can divide the percentage by 100 to find its decimal form.
