The amount of money in geraldo's savings account went from $450 to
$420. explain how to use a negative integer to describe the change.

The savings went from $450 to $420, this means that Geraldo lost $30

This change can be described by the difference between the both savings, this is:

final amount - initial amount = difference

$420 - $450 = -$30

Then the change can be described by the negative integer -$30, this number means that Geraldo "debt" or "lost" 30 dollars.

sorry, i can't understand your question. will later if you describe more clearly!
