Looks good to me! Well done! Tested with NVDA Screen reader

Given	When	Then	Result
QuarterlyFFP table	On staging (not this PR)	current behavior does not read "dollars" out loud when changing the percentages	PASS ✅
QuarterlyFFP table	On this PR	current behavior does read "dollars" out loud when changing the percentages	PASS ✅

@mirano-darren or @tbolt
Can I get more specifics on where I'm supposed to be looking and which fields/content I should be testing? I don't think the language in the code is matching up with the UI, so I'm not sure what I'm testing.

@beparticular
On the Budget and FFP page, specifically the QuarterlyFFP Table, when using a screenreader and changing the percentage values, the screen reader would read the number out loud, but it would not add "dollars" after reading the number. This PR changed it to say dollars after reading out the number.

"Sounds" good to me!
