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.

20%

=

0.2

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

Add the shipping and handling to the price.

$10.32 + $51.60 = $61.92

The total cost was $61.92.
