8. A haircut is $120, how much is a 15% tip? *

18

Step-by-step explanation: 120 times 0.15

$18

Step-by-step explanation:

To work out 15% using a calculator:

0.15 multiplied by 120 which is 18

To work out 15% without a calculator:

10% of 120 is 12. (Just remove the last number whenever you want to get 10% or add it on as a decimal if it's greater than 0. e.g. 10% of 40 is 4 but 10% of 48 is 4.8)

To add the 5% divide 12 by 2 which is 6.

Add the 10% to the 5% to get the 15%.

12+6=18
