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.

10%

=

0.1

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




		8	6

×	0	.	1

	8	.	6

Add the tax to the price.

$8.60 + $86.00 = $94.60

The total cost including tax will be $94.60.
