$81.37.

Step-by-step explanation:

The remainder of the $100 after paying for the CD will be her change.

$100 - $18.63 = $81.37.

Answer:

$81.37

Step-by-step explanation:

The equation would be:

100 - 18.63

It may be easier to start by subtracting just 18 from 100 first:

100 - 18 = 82

Then, from 82 subtract .63:

82 - .63 = 81.37

Ultimately, your answer should be $81.37
