If a woman making $28,000 a year receives a cost-of-living increase of 2.1%, how much is her raise?

$588.

Step-by-step explanation:

You take $28,000 divide it by 100. Because you put your 2.1% above the 100 and x above the 28,000, you then cross multiply. Usually the teacher always called it butterfly method.
