Kerry Stutsman has $500 in a saving account earning .45% interest. She is considering buying a 1year certificate of deposit (CD) that pays 3.25% interest. What will be the annual difference in her interest earnings between the savings account and the CD?

Multiply: $500.00 x .0045 = $2.25
Remember to move the decimal two places.
$500.00 x .0325 = $16.25
Then subtract $16.25  2.25 = $14.00
The annual difference will be $14.00
