key idea

A percent is 1 part out of 100.

1%
is
equal
to
1
100
or
0.01.

solution

Write the percentage as a decimal.

15%

=

0.15

Multiply the decimal by the amount of the bill. Multiply as you would multiply whole numbers, then write the decimal point in the answer.


	41.80

×	0.15


	20900

+	41800

6.2700

The tip was $6.27.
