Question

Heather wants to buy a CD that costs $18.63. How much change does she

receive if she gives the cashier $100? Explain and show your work. *

Answer 1

$81.37

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

Answer 2

$81.37.

Explanation:

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

$100 - $18.63 = $81.37.
